AV #211 - Abraham Lincoln H.S. & more AP classes



Part 1 on Less is More. What is essential?

Why is everyone on board with more AP classes at Abraham Lincoln, again?
Have we learned nothing?

“… this next year we’re going to add AP English Language, AP Calculus, AP US History, and more likely either AP Physics or Chemistry.” Abraham Lincoln High School Principal Antonio Esquibel, presenting at the Accountability Clock Hearing before the State Board of Education (Feb. 2020)


Like any good organization, an effective school will establish the right priorities. Chronically low-performing schools often fail to do so, for several reasons. They can feel overwhelmed. There is no end to what needs to change and improve. They find themselves unable to focus on what is essential.

It would help if they realize less is more. Given how poorly their students are performing, given the students’ skills and knowledge at this time, they should recognize they do not need to look like every other high school. Their students are not working at grade level. Focus on that. Much else—is for another day.

This will seem a small point – and I only send it to 50 of you who might appreciate it, or for whom it might be relevant. This might also seem petty, in light of Covid-19. But this fall almost 1,000 students will enroll at Abraham Lincoln High School (year 5 - again - on the accountability clock). Thousands more will attend dozens of chronically low-performing schools. They deserve better. Given the loss of school time this spring, it is even more critical that we make the best decisions to address the needs of our lowest-achieving students. What are the right priorities? What is essential—for each school? 

As Dr. Anthony Fauci might say, that depends on the evidence. On the facts on the ground. But last February the State Board of Education did not have several key facts—that I will present here—when it approved of Abraham Lincoln’s Innovation Plan. I find that incredibly disturbing. Was DPS equally unaware of these facts? A state, a district, and a school trying to serve its students should do better.

The State Board did see these facts: A slide spoke volumes about the academic skills of Abraham Lincoln students go to Addendum C. Its shows: DOES NOT MEET in every category for high school level skills. Here I add an equally grim picture of how students at Abraham Lincoln have performed on the SAT, one way that Colorado measures college-readiness. (Similar to results at other low-performing high schools.[i])

If we know these facts about the students in the building—on average, nowhere close to demonstrating grade level achievement in English or math—how is it possible that Principal Esquibel could make the case that what the school really needs are many more college-level classes?

If you were present at that accountability hearing last winter, follow this sequence. State board member Jane Goff asked about the Advanced Placement courses at the school. She mentioned the Colorado Education Initiative and its Legacy Grant to support dozens of schools as they added more AP courses.

Superintendent Susana Cordova gave a positive account (Addendum A) of how the Denver Public Schools has expanded its AP offerings this past decade and has received awards for doing so. As an overview, mostly accurate. But it was not relevant to Abraham Lincoln’s AP story. No school specific facts.

Cordova then turned to Principal Antonio Esquibel to discuss the AP program at Abraham Lincoln. Esquibel served as principal before, from 2006-11; he was reassigned to the school last summer. His comments, below, left column, tell a different story than the one I have reported since 2013 in Another View, right-hand column. (Addendum B provides supporting data from those newsletters.)

Differentiation

But first, let’s be clear. Our lowest-performing schools have hit bottom. They are, by definition, not like other schools. They have struggled in vain, for many years, to climb out of the cellar. “What we do as a district” (such as, add more AP classes) is the last thing they need to hear.

The word we use in our classrooms is differentiation. As teachers we try to adjust how we serve our students based on where they are performing and what they need. The same applies to schools. For many high schools, adding AP classes has been a good step. But as I have argued (beginning in 2013 with AV#95), it was never in the best interest of schools like Abraham Lincoln, Aurora Central (AV#114), or Sierra High School (AV#186). In each case the AP initiative produced terrible results.

These results were never the fault of the students. It is we, the adults, who have failed. We have failed to appreciate the difference between an Abraham Lincoln and an East High School. Based on that hearing in February, I doubt that the State Board, DPS, or Abraham Lincoln’s own principal can see the difference. I will try, again, to show that the AP initiative has not worked. It is not too late for Lincoln to change course.

Principal Esquibel
But the facts are …
“In terms of the CEI, when I was principal there [at Lincoln] before, we were the first school in Denver to be a partner with the Colorado Legacy Grant, so [I’m] very familiar with that.”*

“When I was there before we built out a strong AP program, we went from the number of AP classes from 6 courses to 16 courses within about three years, so that that’s the plan again.” 





























“Unfortunately, I think right now Abraham Lincoln has very few AP offerings, none in the core content areas. Predominantly it’s in Spanish and it’s in some of our elective course offerings - in art and computer science, which have been very successful.”

“In our new plan we are going to start to increase AP offerings in the core content area. Specifically, this next year we’re going to add AP English Language, AP Calculus, AP US History, and more likely either AP Physics or Chemistry.
… there’s a lot of training that has to happen, so that is going to help with the rigor overall in the building when we have more teachers trained in AP.”
Esquibel was principal a decade ago, from 2006-2011.
CEI—then called the Colorado Legacy Foundation (CLF)—did not pilot its work until the following year, 2011-12, and that was in three high schools in the Colorado Springs area.
2012-13: CLF expanded its work to 10 other Colorado high schools, including Abraham Lincoln – yes, the first DPS high school to participate.
2013-14: CLF’s AP Initiative added 10 more schools, two of them in Denver: South High and Thomas Jefferson. So yes, Lincoln was the first DPS high school in the “partnership,” but not during Esquibel’s tenure.

“a strong AP program” – Esquibel had increased the number of AP courses offered and of students enrolled by the time he left in 2011. But the passing rate on AP exams (scoring a 3 or better) was 20% in 2010 and 15% in 2011. The next two years the passing rate remained under 25%, even with strong results for AP Spanish Language.
But remove the Spanish Language exams and we see that less than 14% passed their other AP exams all four years (see Addendum B.)

CEI’s work[ii] had successes at many high schools, but not at Abraham Lincoln.
·         Year one of CEI’s AP Initiative at the school: 3% (7/187) pass (3 or better)
·         Year two: 11% (19/176) pass.        
·         Year three: 10% (18/183) pass.                  

(NOTE: National pass rate on all AP exams: 
         2014: 59.2%        2015: 57.9%[iii])

Although the Colorado Education Initiative consistently failed to be transparent about the results for its AP Initiative, my newsletters presented the district data that revealed the dismal passing scores for schools like Abraham Lincoln and Aurora Central (also one of the 10 high schools in CEI’s 2012-13 cohort).

In 2013, 0 out of 40 passed the European History AP, and 1 out of 37 passed the Physics B exam.






In 2014, 0 out of 37 passed the English Literature AP, and 3 out of 86 passed the English Language AP.





In 2015, 3 out of 33 passed the Biology AP, and 1 out of 53 passed the English Language AP.





Did the Legacy Grant help Abraham Lincoln’s overall performance? No. It was rated a school on Priority Improvement when Esquibel left in 2011. Its rating rose to Improvement for two years, but in 2014, year 2 of the Colorado Legacy Grant, its rating dropped to Priority Improvement, where it has been ever since. (One sees a similar trend at Aurora Central and Sierra High. Perhaps the AP Initiative distracted them from more essential matters.)

 “very few AP offerings” – True, the numbers fell before Esquibel returned last summer. Almost 500 AP exams were taken in 2015 (pass rate -20%); in 2019, just 60. (But that year 40 of those tests received a 3 or better, an impressive pass rate of 67% - Addendum D. It would help to have details – e.g., how many of those passing scores were in Spanish Language, Lincoln’s strong suit on AP tests?  Sadly, DPS no longer provides such test-specific data.)

This reduction in AP offerings might have been exactly what the school needs—less time and effort devoted to college-level classes where only a fraction of students was able to earn a passing score of 3.



“very successful” – Perhaps, but how do we know? From 2011 through 2015, the number taking Computer Science exams was 13 or less so we have no data on the number passing. CEI’s initiative stressed math and science, but during those three years (2013-15), even fewer Computer Science exams were taken.

What evidence is there that training to teach AP classes improves the rigor of a teacher’s classroom? Or that, in this school, it is a good use of the limited dollars and resources for professional development? Wouldn’t it make more sense to help teachers at Abraham Lincoln learn how to raise the achievement level of those—the majority of their students—who are not yet at grade level? “More rigor” is a worthy goal, but not this way.

Why Why Why
Not once did Principal Esquibel provide a rationale to the State Board for making this “new plan” (same as the old plan) on expanding AP courses. Was it because it’s what other comprehensive high schools do? Why would DPS—which should have seen the same data I have been looking at since 2013—accept that this time it is the right idea? This school—all our lowest-performing high schools—must have different priorities. The facts show us the folly of Lincoln’s plan. Facts I have presented before—see Addendum B. Haven’t we learned anything?

Addendum A – Superintendent Cordova: district level information on AP courses

Superintendent Susanna Cordova’s response to a question from the State Board of Education (Feb. 13, 2020). (https://www.cde.state.co.us/cdeboard/sbemeeting-20200213-1)

“The Denver Public Schools, for seven years running, has been an AP district of distinction.*

“We have on an annual basis outpaced national averages in the numbers of underrepresented students taking and passing AP classes.**

“We have significantly increased the number of students district-wide who participate in our AP program, and that is alongside significantly increasing the number of students who are taking and participating and passing concurrent enrollment classes.

“So both, we believe, are very valuable rigorous coursework options that give students pathways post-high school … and certainly Lincoln has been part of that.”

*DPS received this honor five times, including four times in a row, 2016-2019, but was not given this award for the most recent (10th annual) Honor roll. https://apcentral.collegeboard.org/pdf/ap-district-honor-roll-10th-annual.pdf

**“AP Test Results” produced by Denver Public Schools’ Accountability, Research and Evaluation unit does indeed show that, overall, the number of underrepresented students in DPS taking and passing the past five years increased. However, so has the gap between the average score across the district and scores for African American (gap is now 22.2% pts.) and Hispanic (now 13.5% pts.) students. Data below is from the district’s two most recent reports, 2014-2018 and 2015-2019):

Addendum B – From past newsletters

Another View #95- Mismatch – Adding more AP classes in low-performing high schools – Why the push to expand AP classes in schools where so many students fail to achieve qualifying scores? (March 26, 2013)

“How well does it serve students to be in courses where most of them do not 'pass' the test that is meant to signal satisfactory knowledge of the material?  AP scores range from 1 to 5; a 3 is considered a passing or 'qualifying score.'  Consider that:

·         In 2011 out of 35 students at Abraham Lincoln taking the AP test in English Language and Composition, only 3 passed.  In 2012, the number taking the test more than doubled; 77 took the test, but only 4 passed.  At Lincoln, in 2012, of the 24 students who took the AP in Physics, not one passed. (Lincoln is now in its first year receiving full support from the Colorado Legacy Foundation as part of the NMSI effort.)”
·         2012 pass rate (3 or better) at Abraham Lincoln: 24% (100/421)
·         Strong results on the Spanish AP – 82% (54/66). Without those scores the % passing AP tests was 13% (46/355).

**

Another View #114 – Questions continue on rationale for more AP classes in our lowest-performing high schools (June 4, 2014)

   In the first year of CLF’s initiative with Abraham Lincoln, the percentage of students passing the AP tests was unchanged [24%]; less than one-quarter of the AP tests were scored at a 3 or better.
   
“… a closer look at the results at Abraham Lincoln, with and without the AP Spanish test, reveals the consistently low percentage of students who pass the other tests.”

For context – In 2013, the passing rate on AP exams for Denver Public Schools was 37.3%.
For Colorado, 62.2%.
For the nation, 58.9%.


“In 2013 the pass rate on the Spanish AP at Lincoln was 82% (68/83) … Such stellar results show that this college level course is a good fit … But separating those figures from the other AP tests taken reveals shockingly low passing rates: English Language & Composition: 3 out of 75 earned a qualifying score; Physics B: 1 out of 37; European History: 0 out of 40. When Spanish AP results are not included, the passing rate …  falls from 24% to 11%.”

Another View #126 AP Results - What the Colorado Education Initiative Won’t Tell You (Feb. 3, 2015)

   “My argument all along – in my first piece on this issue (AV#95 – Mismatch – Adding more AP classes in low-performing high schools) and last year – has been that the AP Initiative is an inappropriate choice for schools where most students perform below grade level.  It does not address a much bigger problem. Abraham Lincoln High School in Denver has been my prime example—but it is not alone.”

  “By now Denver Public Schools and its principals must question if more AP classes—which is no doubt an excellent idea where a good number of students demonstrate they are ready for such college level work but have had not access to such an opportunity—is what a school like Abraham Lincoln needs.”

[Followed by a look at the equally low passing scores – 4% (4/108) – on AP exams other than Spanish Language at Denver’s Bruce Randolph High School.]

   “Sufficient evidence, wouldn’t you agree, to say: STOP! Far better to develop curriculum and instruction that meets these juniors and seniors where they are–most of them not yet performing at grade level–and to help them make as much progress as possible. Classes where they find success, improve their skills, and—one hopes— graduate without needing remediation in reading, writing, and math once they enter college.”

Excerpts from OPEN LETTER TO: Denver School Board and Staff (March 7, 2017)

   “… when the far majority of students in a number of high schools are unable to score a 3 or better on the AP tests, I am convinced we must, instead, create courses that better meet their needs rather than stating that merely ‘taking an AP course’—whether you get a 3 or better—has proved worthwhile.  I find no such proof.  CEI used to make this claim; schools like Delta High, part of CEI’s cohort 2, should stop making it[iv].  (See the quote from Trevor Packard of the College Board).”

  “If the ‘passing rate’ looks low at under 30% or under 20%, imagine what it would be if these schools did not have many students doing well on the Spanish AP, scoring a 3 or better. One example: Abraham Lincoln.  In 2016, 58% of students at Abraham Lincoln taking the Spanish AP passed.  But only 8% of 78 students taking an AP test in English passed, and 5% of 127 students taking AP tests in STEM classes passed, and only 1% of the 79 students taking an AP exam in History and Social Sciences passed.”

AV#186–AP results shows failure of CEI effort in a low-performing high school (Nov. 14, 2018)

“…we should be glad to see the details of AP results at two APS and DPS low-performing high schools, Abraham Lincoln and Aurora Central, schools like Sierra High that CEI never should have included in its AP push.  But again – ever since I included their AP results in previous newsletters – we see little to nothing.

CEI states:
Our Colorado Legacy Schools (CLS) initiative works with 47 high schools across the state to dramatically increase the number and diversity of Colorado high school students who are succeeding in AP math, science, and English courses — especially students typically underrepresented in AP courses such as females, and students of poverty and color.”

“A ‘dramatic increase …’  As I have shown before, this never happened at Abraham Lincoln and Aurora Central. I had hoped anyone who studied the alarmingly poor results of CEI’s effort there would have agreed.  And – while not a clear cause and effect, but a factor – the schools continued to falter.  Are we able to admit our mistakes? Can we see when our desire ‘to help’ is misguided, even harmful?”

Accountability. Transparency. Facts.

“What would I like to see? No more opinions about how we can make our high schools more equitable by providing greater access to students who have previously not had the opportunity to take rigorous college-level classes. No more arguments about how the results at a school like Sierra High fail to take into account the benefits of merely taking a more rigorous courses, whether the student earns a passing rate or not.  We are familiar with such points. What we have not seen lately – from CEI, DPS, or APS – are the results of the AP expansion in our state’s lowest-performing high schools.  That is what I look for.   Once such data is made public – I have not lost hope – then we might have a discussion based on the facts.”



Addendum C – “Accountability Background Report” – Abraham Lincoln

CDE’s Deputy Commissioner Alyssa Pearson presented to the State Board the 2017, 2018, and 2019 PSAT and SAT data for the high school. It reported DOES NOT MEET in all categories all three years.

Below – my own chart similar to what Pearson showed the State Board on Feb. 13, 2020. Limited to just the past two years, with the addition of the percentile rank for student groups.*

*2010-2016 - From Accountability, Research & Evaluation office at DPS. 2010-2016 broken down by subjects tested.

**These 2017 figures jump out as being hard to believe, as they are so inconsistent with what we see in the previous years and the ensuing year. I asked DPS if it might be an error, and received this email response from the Research and Strategy Manager: I am confident there is not a reporting error, and I don’t particularly find the Lincoln’s results odd. As you know, rates can be influenced by a number of factors (number of tests taken, teacher, subjects tested, class of students, etc.” (Nov. 2, 2018)

Is it any wonder passing rates on AP course at these schools are so low?

[ii] CEI’s AP Initiative in its Legacy Schools in Colorado focused on courses in Math, Science, and English, so the percentage of student passing related to CEI’s Initiative is specifically on those courses and exams. At other places in this newsletter—it should be clear where—the percentage passing given is for ALL the AP courses and exams at Lincoln for that particular year.
