Charter schools hold their own on state tests

My preliminary analysis found the following:

Regular Schools: Percent Meeting or Exceeding Growth Standard*
District: 71.4 percent (1591/2227)
Charter: 64.3 percent (54/84)

Regular Schools: Performance Composite
The percentage of school-wide test scores at or above proficient.
District: 71.3 percent
Charter: 70.4 percent

Regular Schools: Average Growth
Minimum expected growth is 0.0
District: .06
Charter: .06

Alternative Schools: Percent Meeting or Exceeding Growth Standard*
District: 89.3 percent (67/75 schools)
Charter: 85.7 percent (6/7 schools)

Alternative Schools: Performance Composite
District: 32.5 percent
Charter: 36.4 percent

Alternative Schools: Average Growth
District: .27
Charter: -.16**

* With the huge disparity in the number of schools, comparisons between district and charter schools should be made with caution.

** Charter growth without the now defunct Baker Charter High School was .06. With a -1.25 average growth, Baker Charter obviously skewed the charter average significantly.
