Labour Relations Board ruling and Summer School

The Labour Relations Board (LRB) ruling of June 27, 2014 provides criteria to be utilized by school districts in determining the status of Summer School in each district. The LRB determined summer school will be limited to:

Remedial programs for students in Grades 10, 11, and 12 who have failed a course(s) and have no choice but to repeat the course(s) in the 2014 Summer School.
Students who cannot take the failed course during the following school year.
In an analysis of student registrations as of June 27, 2014 at 5:00 p.m., secondary school timetables and program options for the 2014-15 school year and availability of Distance Learning options for the 2014-15 school year, it was determined that School District No. 57 Summer School could not proceed. Registrants do not meet the Labour Relations Board criteria and School District No. 57 is able to provide learning options required and stipulated by the Labour Relations Board ruling during its 2014-15 school year.

Secondary School principals are aware of the Labour Relations Board ruling and will ensure that Graduation Program requirements for your child will be addressed upon his or her return to school in the fall.
