UPDATE: TRUESCORES blog post: Trends in Alternative Assessments (with links and resources about/for the "2-percent" group)

I recently discovered an interesting post, Trends in Alternative Assessments, written by Natasha J. Williams, Ph.D., Senior Research Scientist, Psychometric and Research Services at Pearson. The post was published in the TRUESCORES blog, and raises some very good points regarding the assessment of students who are assessed using the "2 % test", a term used in educational circles that describes alternative assessments that are given to students who have cognitive disabilities. One of the goals behind this is to measure AYP (adequate yearly progress.) for this group of students.

At the high school level in my state, North Carolina, the "2-percent test" refers to the OCS Extend 2 exam. Many of the students within this category are classified as Intellectually Disabled, Mild,  and function cognitively  below the 3rd percentile for their age -  at or below two standard deviations from the mean.  The OCS Extend 2 exams were recently eliminated in North Carolina.  Current 9th grade students in the OCS program will be required to take Algebra I, Biology, and English 9 exams at the end of the 10th grade.  A cohort of students will take these exams at the end of the current school year. 

How will these changes impact they way we conceptualize and measure transition outcomes for these students?  In the US, in many high school,  students who receive special education services have a much higher drop-out rate when compared with their peers.   We haven't solved this problem!   Those within the "2 percent" range need a high degree of support to develop the skills needed join the workforce and participate more independently within the community.

Here are some quotes from the  blog.  I encourage you to read the original post!

"There are differences in opinion about how students should be performing on the 2% test. If students perform poorly is that to be expected because they shouldn’t be able to perform well on grade level material or does that indicate that the test has not been modified enough for these students to be able to show what they know? If students perform well on the assessment does that mean that the modifications have been done well or that the wrong students are taking the test? We would like to think that the intent of the legislation was for states to develop a test that assesses grade-level content in such a way that students could be successful. Even so, we have heard the argument that if students taking the 2% test are not doing well they are still performing better than they would have if they had taken the general test."


"Growth models for both the 1% and 2% assessments are also being developed. Again, the type of growth expected from the students taking these assessments is questionable, especially for the 1%. The question is how to capture the types of growth these students do show. Models are being implemented now, and we are curious to see what the evaluation of these models will show. Are we able to capture growth for these students?"


One of my concerns is that no-one is exactly sure how to appropriately measure AYP for students with cognitive disabilities:

The No Child Left Behind Act and the Individuals with Disabilities Act: A Progress Report (2007)
Scott Swail, Educational Policy Institute, Betsy Brand, American Youth Policy Forum  (National Council on Disabilities).
This 2007 progress reports includes a discussion about  issues related to the assessment of students with disabilities who fall within the lowest 1% and 2% of the population.

"Most interviewees voiced these two concerns: first, education policy needs to recognize that some students will need more time to meet grade-level proficiency standards, and second, we are too bound by the traditional structure of education and the requirement to complete high school in four years."  Recommendations begin on page 97.
