I have submitted this to the ProJo, but thought I would give you an advanced peek. I will just say that over the 2-ish years I have been doing this it seems that the more you dig the more you find.
Welcome to Lake Wobegon, RI
After reading the recently released public school achievement test results from the New England Common Assessment Program (NECAP) and then comparing them to the well-respected Nation’s Report Card- also known as the National Assessment of Educational Progress (NAEP), I couldn’t help but think I was in Lake Wobegon because it looks like all of our students are above average.
Every two years the U.S. Department of Education uses the NAEP test to determine how many students are “proficient” in a given discipline, which is defined at “at or above grade level.” But the Rhode Island Department of Education, as does every State, develops their own test and defines their own grade level expectations. So when a State declares it has achieved an 80% proficiency rate, it is quite likely that the Federal Government would find a proficiency rate far lower.
It is important to remember that the federal “proficiency” defines our progress towards the goals of No Child Left Behind.
In research published by the Ocean State Policy Research Institute last year, we documented a mapping formula that allows us to estimate NAEP scores for individual schools when only state test scores are available. This allows us to estimate NAEP scores during non-testing years and to compare RI schools to those in other states.
In 2005 the NAEP test found 29% of RI student to be “proficient” in reading but the same year’s NECAP scores labeled 55% “proficient.” When tested again in 2007, the NAEP results went down to 27% while the NECAP rose to 61%. The latest NECAP results continue the rise to 65% but our estimates place the NAEP equivalent down to 26%.
As you can see by the graph, not only is there substantial disparity between federal and state “proficiencies” but the trends are going in the opposite direction. Its like one is using a yardstick and the other a meter-stick, and one of them is upside down.
Looking at the school level is where we see the impact on shareholders.
Parents of Barrington 8th grade students who are proud to hear NECAP claim proficiency exceeding 90% become less enamored when the federal guidelines place nearly one third of those students below grade level.
And parents in Providence can’t be happy with the NECAP results showing 72% of their 8th grade children below grade level in both math and reading, but they would be justifiably outraged if they knew that NAEP estimates put that number at over 90%.
Our research has identified two problems: the disparity between state and federal “proficiencies” and the trend for 8th grade reading going up according to the NECAP test but doing down according to the NAEP test. We have also reviewed other states and found them all to show inflated scores but only 12 other states have been found with the divergent trends.
The Rhode Island Department of Education openly admits that NECAP and NAEP “proficiencies” are two different measurements. The NECAP “proficiency” more closely aligns with NAEP “basic.” But we believe they should be the same and agree with what Senator Ted Kennedy wrote in the New National Defense Education Act, S. 3502, “Student performance varies greatly between some State-level assessments and NAEP assessments. (sic) [I]n today’s global economy, students must prepare to compete with students from other states and other nations.”
As to the problem of rising NECAP reading proficiencies and lowering NAEP scores, our research indicates the problem is most likely due to a state curriculum with a narrower content range than that of the NAEP. This theory is further supported by the fact that we find the same phenomenon in New Hampshire, which also uses the NECAP.
Imagine that NECAP teaches from a 100 page book while NAEP teaches from a 500 page book. Since the same number of sample questions are released for both the NAEP and NECAP, the questions for the NECAP represent a substantially larger portion of the total curriculum to be tested. So, over time, teaching to the test (which normally isn’t a bad thing) becomes progressively more effective.
But that is just a hypothesis. Further study is needed. Consideration should also be given to conducting the assessment function through an independent agency to remove concerns about conflicts of interest. When we published this research in Oklahoma, Senator Clark Jolley introduced legislation to remove testing from the auspices of the Department of Education.
Obviously, Lake Wobegone is a fictitious place if only because it is statistically impossible that “all the children are above average.” Rhode Island, and all states, should measure student performance with the same yardstick so parents know how their children stack up against those they will be competing with, because they won’t just be competing in Minnesota.
