4. Illustrative Example: Impact of Class Size Increase by One on 2009-2010 Elementary Staffing
Based on a class size increase of one student on enrollment, schools would have seen a reduction of 20 elementary classes
Kindergarten – decrease of five classes countywide
Grades 1–5 – decrease of 15 classes countywide

5. Capacity Numbers: MGT & APS
Differences in capacity numbers due to four reasons:
Variation in formula (same number of rooms)
Current use vs. potential use
Clarity of detail due to 30,000 foot view from MGT
Adjustments to room uses not yet captured by APS (last capacity update Aug 09)

6. Enrollment Projections: MGT & APS
Differences in projection numbers due to variation in methodologies
APS selects a single methodology
MGT uses a combination methodology
APS staff and MGT are confident in APS’ methodology
Historically accurate within 2% systemwide
Updated twice yearly
