Rally held at Manual High School to encourage parents to opt out of CMAS KMGH and last updated 2021-02-28 19:20:26-05 DENVER -- It's been a whirlwind of a year for students, parents and teachers, and that frustration was felt at Manual High School during a rally Sunday afternoon in favor of opting out of CMAS testing. The pandemic has disrupted traditional learning, and some parents feel now is just not the time to test these kids. "Our daughter is devastated not being with her friends. This is our final year in elementary school, and she's just completely devastated," parent and educational researcher Danielle Walker said.
