The ARC process includes terms that may be unfamiliar. Please see the Glossary of Terms below for an explanation of some of the lesser-known terms that will be used during the process:

Family of Schools: Group of schools that may be included as part of the accommodation review process based on their ability to address the overall accommodation issues.

Long-Term Facilities Master Plan: A comprehensive planning document illustrating the condition and utilization of current facilities, and possible accommodation solutions designed to enhance student achievement.

Preliminary School Accommodation Review Report: Initial report to the Board of Trustees outlining the rationale and scope of a potential accommodation review.

School Information Profile: Contains data to help the Accommodation Review Committee (ARC) and the community understand how well the school(s) meet the objectives and the Reference Criteria outlined in the Terms of Reference.

Terms of Reference: Outlines the mandate, scope, reference criteria, operating procedure and structure of the ARC.


Average Daily Enrolment (ADE) is the calculation of the number of students enrolled in a school based on two count dates within the academic year – October 31 and March 31. The ADE total is calculated by averaging enrolment at the school during these two time periods and is meant to capture the second semester decline in enrolment as a result of students who graduated at the end of the first semester and have left the system.

Head Count is the actual number of students attending a school at any given time for any given program.

Full Time Equivalent (FTE) is the adjusted Head Count enrolment to take into account part-time students.

Facility Condition Index (FCI): A ratio used to measure the relative condition of a building taking into account all building systems. It is calculated by dividing the cost of repairs for the building by the replacement value.

Prohibitive-to-Repair (PTR): Designation attached to a building when the FCI (see above) is equal to or greater than 65%. A high FCI is indicative of the cost of repairs to the building compared to the cost to rebuild the facility. The 65% FCI threshold that results in the designation of a school as PTR was set by the Ministry of Education.

Gross Floor Area (GFA): The total constructed area of a building.

On-The-Ground Capacity (OTG): The rated capacity for a facility (number of students the permanent structure can accommodate) as indicated on the Ministry of Education’s School Facilities Inventory System which is a web-based database containing facility-related data of all schools in Ontario. Depending on the type of room, the space will have a different loading (i.e. secondary classroom @ 21 pupil places). It does not represent the physical limit of the space.

Utilization Rate: The measurement of the physical use of the permanent school facility based on the comparison of Enrolment to the On-The-Ground (OTG) Capacity of the school.

Operating Costs: These encompass all of the expenditures required to operate and maintain the school including heating, lighting, cleaning and routine maintenance.

Administrative Costs: These include all of the expenditures associated with a school’s administration staff including the salaries of the principal, vice-principal(s), secretaries, etc.
