The NAEP results are proof of the effectiveness of earlier reforms, and a testament to the leadership of former state Superintendent Nancy S. Grasmick, who retired after the last school year. But if the state is to continue growing, it cannot afford to rest on its laurels. The Obama administration's Race to the Top competition, which awarded Maryland $250 million in federal dollars to fund its school reform effort, has been a tremendous stimulus to educational innovation in the state. Whoever the state chooses as a permanent replacement for Ms. Grasmick must share her belief that no matter how highly Maryland may rank on national measures of education, the state must continue pushing forward with reforms. Maryland's progress has been impressive, but progress isn't enough.
