CAC – Campus Advisory Council; a campus level advisory council, required by state law, that addresses the concerns of school communities.

Campus -A site where one or more schools/buildings is/are located. For example, an elementary school can share a site with a middle school; therefore, it is considered a campus.

Capital Cost Avoidance – Strategy that allows the deferral or elimination of projected capital expenditures, to improve a permanent structure or aspect of a property.

Capital Improvement - The addition or restoration of a permanent structure or some aspect of a property that will either enhance the property's overall value or increase its useful life.

Closure: (Accountability) - Cessation of all instructional activity on the campus in each grade level served in the school year immediately preceding the closure of the campus. An order of closure does not preclude the district from reusing the facility for another purpose such as administration, storage, or instruction in other grades not served during the school year immediately preceding the closure of the campus.

Closure (Operations) - A school that is no longer open to students.

Cohort - A specific group of students established for monitoring purposes, particularly over time.

Consolidation - When a school is closed, its student population will be combined with another student population in another facility.

Core Spaces -Large areas within a building that are utilized by most students throughout the school day, i.e., cafeteria, gymnasium, library.


Deficiency - A construction deficiency is an item or condition that is considered sub-standard or does not meet current standards or building codes.


Educational Adequacy -An assessment of a facility to evaluate how well the campus is equipped to deliver the instructional program. For example, does the facility have the standard types of technology within the classroom that a teacher requires for the current curriculum? Is there the proper amount of white board space in the classroom? Is there the correct number of lab stations in a science room and do they have the proper equipment?

Educational Specifications - Document that describes the current standards for program areas, equipment needs, technology needs, square footage, and other considerations for a new school.

Enrollment -The number of students attending a school.

Exigent Circumstances - Conditions that require an immediate response.


Facility - A structure or building or a physically related group of structures utilized for a single purpose.

Facility Condition Assessment - An evaluation of a school facility that identifies current building and building system deficiencies.

Facility Master Plan - A Plan that outlines the current status and future use of district facilities, guides the development of future capital improvements, and supports planning for future bond elections. It is a living document and will be reviewed through a recommended review cycle.

FCI -Facility Condition Index; an indicator of a facilities condition obtained by dividing the repair costs by the replacement cost of the same building.

FF&E -Furniture, Fixtures, and Equipment; the moveable equipment that is used by the occupants inside a facility, including student furniture and computers.

Functional Capacity - Used to determine the number of students a school facility can accommodate in any given school year, functional capacity is based on the total number of permanent and portable classrooms on a site, as well as the use of each classroom. Classrooms used for District-wide administration purposes and those used for special education classes are not calculated into the functional capacity for the school. The functional capacity of a school changes as portables are added or removed and decisions regarding the location of District-wide administration staff can increase or decrease the number of classrooms available for students. As these types of decisions can be implemented quickly, the functional capacity of a school may change during the course of a school year. Functional capacity is used in annual facilities decisions such as identifying schools to open or freeze to transfers.

The following describes the functional capacity methodology for elementary schools.

1. Count classrooms within permanent building(s) and portable buildings

2. Subtract the number of classrooms used for special areas such as music, art, and physical education (generally three to seven classrooms based on staffing ratios).

3. Subtract classrooms used exclusively for special education (small class size) and those housing district wide programs or staff (no students)

4. Multiply by 22 (average class size)

5. Apply 95% efficiency factor, 85% efficiency factor for Title 1 schools

The following describes the functional capacity methodology for secondary schools.

1. Count classrooms within permanent building(s) and portable buildings

2. Subtract classrooms used exclusively for special education (small class size) and those housing district wide programs or staff (no students)

3. Multiply by 28 (average class size)

4. Apply 95% efficiency factor, 85% efficiency factor for Title 1 schools

Functional Equity - Comparison of identified core areas and other specialized classroom space and the level at which they meet the AISD educational specification standards.


GIS -Geographic Information System; an automated system for referencing geocoded data, e.g., a database of addresses for students enrolled in a school system.

Guiding Principles - Board defined precepts that are most important to the district in the development of the Facility Master Plan. All of the guiding principles are deemed important by the Board, and they are not listed in any particular order in this document.


HVAC - Heating, Ventilation, and Air Conditioning.


Impervious Cover -Any type of surface that will not allow rainfall or runoff to soak into the ground (e.g. pavement or buildings). Local ordinances may limit impervious cover in developments for environmental protection or runoff control purposes.

In Migration – Students attending a school that live outside of that school's attendance zone.

Infrastructure - Essential facilities and services to support the functioning of a system. Examples include: roads, driveways, parking, electrical systems, communication systems and HVAC.


Joint Use – A sharing of space amongst schools and communities.


Lease Space - Space in a building owned by another party which is contracted by the district for a specified term and rate.


M&O - Maintenance and Operations; school funding that pays for day-to-day administrative and operational costs.


Operating Cost - Costs associated with operating a school facility including administration, custodial and maintenance supplies and staffing, and food service.

Out Migration - Students leaving their attendance zones to attend another school in the district.

Over-capacity - A school enrollment that is greater than 115% of permanent capacity.


Permanent Capacity – Used for long-term planning purposes, permanent capacity is the number of students the school facility is designed to accommodate within the permanent structure(s). The district calculates the permanent capacity of a school by counting the number of classrooms and multiplying by an average student class size and an efficiency factor. Permanent capacity does not incorporate temporary or portable classrooms, but only permanent space.

The following describes the permanent capacity methodology for elementary schools.

1. Count the total number of permanent classrooms.

2. Subtract the number of classrooms used for special areas such as music, art, and physical education (generally three to seven classrooms based on staffing ratios).

3. Multiply the result by 22 (average class size).

4. Multiply by the efficiency factor (95% for regular schools and 85% for Title 1 schools).

The following describes the permanent capacity methodology for secondary schools.

1. Count the number of permanent classrooms.

2. Multiply the result by 28 (average class size).

3. Multiply by the efficiency factor (75% for regular schools, 70% for Title 1 schools).

Portable/Temporary Building -A building designed and built to be movable rather than as a permanent structure. A typical portable building in AISD contains two classrooms.

Priority Facility Condition Deficiency - A categorization of building deficiencies, defined as follows.

Priority 1: currently critical (immediate need, i.e., fire safety systems)

Priority 2: potentially critical (to be corrected within one year, i.e., major HVAC equipment, security systems)

Priority 3: necessary/not yet critical (1-2 years, i.e., site lighting, sanitation sewer, educational adequacy)

Priority 4: recommended (3-5 years, i.e., finishes, educational adequacy)

Priority 5: does not meet current code/standards/grandfathered (i.e., functional equity, 3rd tier ADA)


Reconstitution (Accountability) – Removal or reassignment of some or all campus personnel and the implementation of a campus redesign plan that provides a rigorous and relevant academic program and addresses comprehensive school-wide improvements that cover all aspects of a school's operations.
