State test scores increase again; but is it real? Opt out rates remain high


NYC average proficiency rates in 3rd-8th grade 2013-2017
The NY state and city test scores were released this week.  Proficiency rates statewide increased again though by a smaller amount than last year. In English Language Arts, the percentage of students in grades 3-8 who scored at proficient levels increased by an average of 1.9 percentage points; from 37.9% in 2016 to 39.8%.  In math, the students who scored at proficiency rose to 40.2%, up 1.1 points from 29.1% last year.  

In NYC the increases were a little larger: a gain of more than two points in ELA proficiency to 40.6% and 1.4 points to 37.8% proficiency  in math.  

Commissioner Elia, Mayor de Blasio and Chancellor Farina claimed that the increase in proficiency since 2013 was strong evidence that our students and schools are making progress.

Yet the reality is that the trends over the last 15 years have not matched any of the trends on the more reliable national test called the NAEPs, for either NYC or the state as a whole.  


In fact, the NY State Education Department has appeared unable since 2002 to produce a reliable test and score it consistently enough to allow one to assess if there’s been any sort of improvement in our schools.  Instead, Commissioners and their staff have repeatedly changed cut scores and set proficiency rates to make political points.


There are many ways to show increases in proficiency -- a metric notoriously easy to manipulate -- including making the tests easier, shorter, giving them untimed, and/or changing the scoring by lowering the raw scores to scale scores or the cut scores need for proficiency.  The state has used all these tricks over time.  

From at least 2002- 2008, under Commissioner Mills, there were years of test score inflation, until the questions and scoring became so easy a student could randomly guess their way into a Level 2.

In New York City, the rapid growth in proficiency rates – in 2009 with 82 percent of city students proficient in math and 69 percent in English, up sharply from 42 and 38 percent, respectively, in 2002 -- helped Michael Bloomberg renew control over the schools and cruise to an unprecedented third term as mayor.  (Here are the charts showing gains up to 2008- I can no longer find the ones from 2009.)



Yet the test score inflation became so embarrassingly obvious to nearly everyone that David Steiner, Mill’s replacement as Commissioner, was forced to reset the cut scores to more reasonable levels in 2010, and statewide proficiency rates fell dramatically from 86% to 61% in math, and from 77% to 53% in ELA.  


In NYC proficiency rates fell even more – in math, proficiency rates dropped 28 points to 54% and reading scores dropped 27 points to 42%.


When Steiner was pushed out by Merryl Tisch in April 2011, she replaced him with John King, who aligned the new exams to the Common Core standards – and proceeded to rate more than two thirds of the student in the state as below proficient.  To this end, King made the exams longer and more difficult, and raised the cut scores much higher.  He determined that less than one third of the state’s students would be deemed proficient, by matching the rate with the percent of NY students achieving arbitrarily high marks on the SATs of 540 in math and 560 in reading, far higher than the score of 500 that the College Board has defined as “college-ready.”   


Parents protested, opt out rates soared, and in December 2014, King left in disgrace.   Test scores began to increase once again. Commissioner Elia was appointed in July 2015, and revamped the tests to make them a bit shorter and allowed students to take them untimed.  The state also lowered the level of raw scores equated with proficiency in 11 out of 12 exams last year.


For more on the history of NYS test score inflation see our blog here:
The state tests are still too long, full of abstruse vocabulary, reading passages above grade level, and too many ambiguous questions.  And last year the opt out rate remains high at 19 percent. 
In 2017, 92% of public school districts had opt out rates of more than 5% in math, and 91% of districts had opt out rates more than 5% in English Language Arts– making the results even more unreliable to assess any progress.   Most experts say you need at least 95% test participation rate on which to base any reliable judgements.  (I used the NYSED test refusal file here; and counted NYC as one district and removed charter schools.)

The NYSED press release and presentation emphasized that of “the total test refusals statewide, the most are from average and low need districts.” Similarly, the pro-testing organizations funded by the Gates organization have repeatedly claimed that this is primarily a phenomenon of middle-class suburban parents.  But if you look within districts instead of across them, there is a very different story to be told:  65% of NYS districts had a HIGHER or equal percent of their economically disadvantaged students opting out of the ELA exams than their district-wide averages in 2017; and 75% of districts in math.  Moreover, several high-poverty urban districts had substantial opt out rates, including 12.7% in Rochester, 20.3% in Albany and 15.2% in Buffalo.

There are other anomalies in both the ELA and the math results suggesting that the tests and/or the proficiency levels may be unreliable.  In math, the NYC mean scale score didn’t increase from last year though the average proficiency level did – and the proportion of level one students remains very high, with more students testing at level one in math than any other level in grades 5-8. 

In ELA, the pattern of increases doesn’t make much sense.  Usually proficiency declines with higher grades; while in NYC, the percent of students testing at proficient levels is much larger in 7th and 8th grades than 5th and 6th grades.  Also highly suspect is the fact that the technical report for this year’s state exams hasn’t been released – no less the exams given over a year ago in 2016.
Mayor de Blasio press conference Aug. 22, 2017 

In any case, just like the previous Mayor, Bill de Blasio held a press conference to trumpet the results and explain how the rise in proficiency levels proved his reforms are working. (Video here.) 

He evinced amnesia when he claimed that for the first time, most kids in NYC are near proficiency, saying that at the end of the previous administration only 30% of kids were reading at grade level and that low achievement was "tolerated" by earlier mayors. 
In fact, no Mayor that I remember ever “tolerated” low levels of achievement, and Bloomberg took great credit in 2008 and 2009 when the proficiency rates soared far higher than they are today --  peaking at 69% in ELA and 82% in math, before the bubble burst.  
De Blasio also claimed that no previous administration had really made any effort to close achievement gap "because we didn't start where we could make the most impact which is early childhood education."  

Yet despite the Mayor’s words, early childhood education doesn't end at preK, but according to most experts lasts at least to 2nd grade.  De Blasio deserves credit for vastly expanding preK, but when Rudy Crew was Chancellor, he put focus on expanding preK and reducing class size in grades K-3– both reforms critical for improving learning opportunities and narrowing the achievement gap.  Crew also invested special funding into reducing class size to even smaller levels in low-performing schools, called the Chancellor’s district.

In contrast, this administration has failed to make any effort into reducing class size anywhere – even the struggling Renewal schools.  Accordingly, class sizes remain very high, with more than 300,000 students in classes of 30 or more citywide. 

The number of students in very large classes in the early grades has soared.  More than 20,000 Kindergarten students were in classes of 25 or more last fall, and more than 43,000 1st-3rd graders in classes of 30 or larger – the latter an increase of 4000% since 2007.  The failure of de Blasio to reduce class size as he promised and as the state law requires prompted Class Size Matters,  the Public Advocate and nine NYC parents to file a legal complaint against the DOE to the State Education Department last month.
Will the last two years of state test score gains prove to be as illusory as those which occurred during the last period of test score inflation of 2002-2009?  The NAEPs are only given once every two years, and I will remain skeptical until the 2017 NAEPs are released in January and February of next year. 
All we know is that the recent rise in proficiency and test scores since 2013 at the state and the city level haven’t yet been matched on the NAEPs– which have instead been flat or slightly declining, as shown below.
