This report examines the outcomes of the in-class summer programs operated in Miami-Dade County Public Schools (M-DCPS). The Summer Programs, offered to provide supplemental instruction for students in need of remediation, are comprised of Literacy for Rising 3rd Grade Students, Algebra I End-of-Course (EOC) remediation, and Course Recovery. Not included in this report is the state-mandated summer program for retained third graders, which is addressed in a separate evaluation. Students who participated in the Literacy for Rising Third Grade component enjoyed significantly better outcomes on the iReady Diagnostic Test administered in the fall than students who did not attend the summer sessions. In addition, the Algebra I remediation significantly improved the odds of passing the End of Course exam for summer participants in Grade 11, but not at any other grade. Finally, over two-thirds of the courses attempted by students who participated in Course Recovery were completed (over 45% with a grade of C and nearly 35% with a grade of B), helping students meet promotion criteria.
