The purpose of this rule development is to revise the school accountability criteria and processes and to implement requirements of Section 1008.34, Florida Statutes, including a revision of the minimum required number of eligible students’ scores in reading and math for the school to receive a school grade (10), and provisions for grading co-located schools. Proposed revisions also include a change in the percent-tested calculation to conform with federal reporting requirements, extension of the one-letter-grade drop protection through 2014-15, and technical corrections. These revisions will be effective beginning in 2013-14.
