Indicator 13 is the percentage of youth age 16-21 with an IEP which includes measurable, annually updated postsecondary goal(s) based upon an age-appropriate transition assessment, IEP goals related to transition service needs, transition services and a course of study. Transition services, annual IEP goals related to transition service needs and the course of study should enable the LEA to facilitate the student’s reasonable progress toward achieving their postsecondary goals. As part of collecting data for this indicator, LEAs will provide evidence that the student was invited to the ARC meeting where transition services are discussed and evidence that, if appropriate, a representative of participating outside agencies was invited with the prior consent of the parent.
