Vanguard High School scored a perfect 100% on the writing CSAP for their ninth and tenth grades. Not even one student, of the 55 who tested, scored below proficient!
Vanguard HS is an extension to the Cheyenne Mountain Charter Academy. The secondary school is authorized by the state Charter School Institute while the elementary is authorized by the Cheyenne Mountain School District. The Cheyenne Mountain district wouldn't let the school's leaders use the words "Cheyenne Mountain" in the name for the new high school when it was initially approved. The secondary school's charter subsequently moved to CSI.
