Establishes three-year pilot program in DOE to support school district programs to increase length of school day or school year.

S 1559 establishes a three-year pilot program in New Jersey's Department of Education to help school districts extend school days or years. It targets school districts with high academic need - based on graduation rates, dropout rates, and test scores - with up to 20 districts selected (five from each of three regions plus five more prioritized by need). Participating districts can receive up to $1 million annually to cover new costs like staff pay increases (with union agreement), transportation, or support services, but only for expenses they wouldn't have incurred otherwise. Districts must report student participation, attendance, and outcomes annually, and the state will evaluate the program's impact on student achievement and pandemic learning recovery after three years.
