Notes: The study began with 5,294 in the Preschool special education cohort. Between preschool and kindergarten 22% of these students were declassified. By third grade, an additional 3% were declassified. 70% of declassifications among the preschool cohort by third grade came from those preschool special education students served with Related Services only.

Note: There was some loss of numbers in the preschool cohort due to student mobility. (This is why hand calculating the percent change from the numbers on this chart won't give you the same percent.)

Note that almost every special education student in kindergarten was a former preschool special education student.

Almost no children were newly classified in Kindergarten but after that that the Comparison Cohort grew dramatically from year to year.

Recall from Becky Cort's keynote presentation this morning, that by 3rd grade, schools are discovering from State Assessment data that 1 out of 3 students with disabilities are not reading with any degree of proficiently at grade level (i.e., Level 1) and 1 out of 3 is a struggling learner with partial proficiency (Level 2).
