This is important.
Pay attention, because you might live in an area that doesn’t proactively propose related services in compliance with IDEA, Section 504, and/or implementing state regulations. Too often, my experience has been that if you don’t know to ask, they won’t be proposed.
Related services are supports required to assist a child with a disability to benefit from special education. This could be transportation to tutoring sessions, work with a speech therapist, assistive technology training for the parent and student, training parents to use sign language, providing special training to teachers working with students, and much more.
