Learning Support Program

For individuals applying for our learning support program, RSP, additional documentation is required. Families must submit a recent (within three years) psycho-educational evaluation that shows a diagnosis of a mild to moderate learning disability, NVLD, ADD/ADHD, or any OHI. An interview with the RSP staff is required for all applicants applying to this program. A link to sign up for an interview will be sent out after the application deadline to all families applying for the RSP. Interviews will be held in the end of January/beginning of February.
