By working with parents and faculty, the Learning Support Coordinator guides caregivers regarding learning-related matters. The primary role of the Learning Support Coordinator is to support boys who may not be performing to grade level expectations and/or are experiencing learning difficulties. This support can include any of the following: academic screening, observation of the student in different learning environments, meetings with parents and teachers regarding recommendations to help the student, consultation regarding strategies and modifications, discussion of student work and referrals to external services. The Learning Support Coordinator recruits and advises high school boys who tutor younger students. The Learning Support Coordinator is also involved in admissions screening for RP and Grade 1 and consults with principals at all levels as needed for admissions.
Student Support Services. St. Mary's does not have the facilities to serve children who have serious learning, emotional or physical disabilities and all students are enrolled in mainstream classes. Students must be able to learn in the mainstream classes with a minimum of special assistance. Academic support classes provide mainstream curriculum reinforcement for 7th through 10th graders. Elective writing classes are offered for any boys who may need additional reinforcement of writing skills. High School students are available to act as tutors for younger students in a program supervised by the Learning Support Coordinator.
