Advocates of strengthening – or at least not weakening – the teaching of math and science won a partial victory in the final budget that Gov. Brown signed last week. A second year of science for high school graduation remains a state mandate, at the Legislature’s insistence, contrary to Brown’s proposal to make it optional. However, it’s not among the mandates that will be eligible for a block grant reimbursement of $28 per student – at least not as long as the cost of the program is tied up in litigation. The administration contends that the methodology for calculating the $250 million cost for reimbursing districts for second-year science – an IOU that’s been mounting up – is flawed.
