Suspension and Expulsion Rates

SPPI 4B Calculation and Example  (PDF)

The State's definition of "significant discrepancy" provides that any local education agency (LEA) meeting the State's established minimum size requirement (MSR) and exceeding the established risk ratio threshold of greater than 3.0 (3 times the rate of non-disabled students) for out of school suspensions and expulsions of greater than 10 days in a single school year for children with IEPs would be identified as such. To be included in this measurement, an LEA must have at least 30 total students served in special education during the school year measured on applicable attendance reported AND have at least 10 students ages 3-21 served in special education with applicable action codes for out of school suspensions and expulsions that equal more than 10 cumulative school days. If the LEA meets MSR, the rate of students ages 3-21 served in special education with out of school suspensions and expulsions greater than 10 days is divided by the rate of nondisabled students in the same LEA with out of school suspensions and expulsions greater than 10 days to determine the risk ratio. An alternate risk ratio is applied when the target group meets MSR, but the comparison group in the LEA does not meet the MSR requirements. The calculation is performed by dividing the rate of children with disabilities for out of school suspensions and expulsions of greater than 10 days in a single school year within an LEA by the risk of that outcome for nondisabled students in the State. No risk ratio or alternate risk ratio is calculated in a particular category for an LEA if the target group being analyzed does not meet the minimum cell size (10) or minimum n-size (30).

To be included in this measurement, an LEA must have at least 30 total students in a particular racial/ethnic group served in special education during the school year measured on applicable attendance reported AND have at least 10 students ages 3-21 in a particular racial/ethnic group served in special education with applicable action codes for out of school suspensions and expulsions that equal more than 10 cumulative school days. If the LEA meets MSR, the rate of students ages 3-21 in a particular racial/ethnic group served in special education with out of school suspensions and expulsions greater than 10 days is divided by the rate of nondisabled students in the same racial/ethnic group in the same LEA with out of school suspensions and expulsions greater than 10 days to determine the risk ratio.
