This paper presents an addendum on Massachusetts Comprehensive Assessment System (MCAS) Academic Support Programs for the fiscal year 2006. This addendum supplements the report submitted in January 2006 regarding MCAS academic support programs for students who had not yet passed the grade 10 English language arts and mathematics MCAS tests required for high school graduation. Since that time, funded programs have submitted their end of year student data to the Department, which allowed this report to include more complete statistics. Approximately 14,000 of the 67,000 eligible students from the Classes of 2003-2009 have been served through this line item. The data presented illustrate that students served by these programs earned their competency determinations (a state graduation requirement) at rates 21 percentage points higher than their eligible peers who did not participate in these programs. Furthermore, this report shows that this also holds true when looking at students by class year as well as by special population, including special education, limited English proficiency, and low-income status. Appendices include: (1) Entities Funded for FY 06 MCAS Support Programs through Line Item #7061-9404; (2) Additional Information on Data Used in Report; and (3) Chapter 45 of the Acts of 2005, line-item 7061-9404. (Contains 7 tables and 4 footnotes.)
