SPPI-13 measures the percentage of youth with IEPs aged 16 up to age 21 with an IEP that includes:

• Appropriate measurable postsecondary goals that are annually updated and based upon an age-appropriate transition assessment;
• Transition services, including courses of study, that will reasonably enable the student to meet those postsecondary goals and
• Annual IEP goals related to the student's transition service needs.

Additionally, there must be documented evidence that the student was invited to the admission, review, and dismissal (ARD) committee meeting where transition services are to be discussed and evidence that, if appropriate, a representative of any participating agency that is likely to be responsible for providing or paying for transition services was invited to the ARD meeting with the prior consent of the parent or student who has reached the age of majority.
