Ruth Rodríguez Fay: 'Achievement gap' based on MCAS, racist test designed to indoctrinate Ruth Rodríguez Fay The so-called “achievement gap” is solely based on MCAS, a racist, eugenics test that was designed to indoctrinate, not educate our Black and Latino students. As Boston Globe columnist Derrick Jackson points out in his opinion piece, “MCAS is still racist,” because the test fails to include any Black history questions. As a panelist on Harvard's School-to-Prison Pipeline, I sat on a panel with a Suffolk County Juvenile Court judge who found that, “since the MCAS became a high school graduation requirement, he witnessed an increase of youth before his court of over 200%, the majority who were Blacks and Latinos, and over 95% had failed the test.”
