The various Support Services at St John’s are working closely with all teachers in a shared purpose of enabling the individual student to thrive physically, academically, creatively and personally. The services of Speech and Language therapists and an Occupational Therapist are also available upon request from teachers and parents. Therapy sessions can be arranged during or after the school day. The speech and occupational therapists work on a free-lance basis; therefore their services incur an additional charge, not included in the school fees.
