For Destreamed classes, the maximum class size should be 20 students per teacher 4. Identified Exceptional Students, as defined in Bill 82, placed in regular science classes should be regarded as the equivalent of two mainstream students. New and renovated secondary school laboratories must meet the Ontario Building Code regulation of 4.60 m2 space per person. However, no matter how large an existing lab shall be, no more that 24 students shall be assigned to it at any one time. The amount of space needed to carry out student investigations depends on such variables as the nature of the course, whether or not the laboratory is also used for classroom discussion, and how much the laboratory is used for student independent investigation.
Common sense says that overcrowing in science laboratories creates potential safety hazards.
These hazards may be reduced by adhering to the OBC regulations.
