Notes:  See Part B child count data notes for an explanation of individual state differences.
 
Percent = Number of students ages 6 through 17 served under IDEA, Part B, divided by the number of students
age 6 through 17 in the population multiplied by 100.  See Table 1-4 and 1-5 for the numerator and Table C-4 for the denominator.
 
The sum of the percentages for individual disabilities may not equal the percentage of all disabilities because of rounding.
 
. Percentage cannot be calculated.
