The 2001-2002 reporting system introduced the use of annual learning gains.  This new method bases a portion of the school's grade on the measurement of each student's progress form one year to the next through annual learning gains.  Another way a school can increase its grade is by the proportion of students that achieve high scored on the FCAT.

How the 2001-2002 system works:

Scoring High on the FCAT - Schools earn points for each percent of students that score average to above average in Math, Reading and Writing.

Making Annual Learning Gaines - Schools earn points for each percent of students that increase an achievement level in Math, Reading and Writing.  Points are also earned for each percent of students that stay at higher achievement levels.  

If a school that otherwise would be graded B or C does not make adequate progress for two years in a row, its final grade is reduced by one letter grade.  If less than 90% of a school's students were tested, the school will automatically receive an F.
