When Gov. Susana Martinez was sworn into office nearly eight years ago, she had this to say about educating children in New Mexico: “Nothing we do is more indispensable to our future well-being or will receive more attention from my administration than guaranteeing our children a quality education.” New Mexico had received an “F” for K-12 achievement on a national education grading report. Fast forward eight years. As she winds down the final year of her second term, New Mexico earned a “D-” for K-12 achievement from Education Week’s Quality Counts report — and our overall grade actually sunk from a C to a D, dropping from 32nd to 50th out of the 50 states and the District of Columbia. There’s more to learn about that progress — or lack thereof — in trying to improve education in New Mexico, other than “it’s hard.” Turning around a system as large as public education is like turning an aircraft carrier.
