Achievement First is a Connecticut-based charter chain known for its no-excuses style, akin to schools of the late 19th century.

Data released by the Rhode Island Department of Education show that one of the AF charters in Rhode Island has a sky-high suspension rate.

The school in question is a K-4 school.

PROVIDENCE — A charter elementary school run by Achievement First had among the highest out-of-school suspension rates in the state during the last school year, according to data recently released by the Rhode Island Department of Education.

The Achievement First Providence Mayoral Academy, a kindergarten-through-grade-4 school, has the fourth-highest suspension rate in the state among all schools, at 47.5 incidents per 100 students. The rate represents the total number of suspensions, not the the number of students suspended. Some students may have been suspended multiple times.

The academy has 460 students. Achievement First has a total enrollment of 1,127 students.

The only schools with higher rates of suspension were an alternative academy in the Charlestown, Richmond and Hopkinton school district, the West Broadway Middle School in Providence, and Hamlet Middle School in Woonsocket.

Among elementary school children from low-income families, Achievement First has the highest rate of suspensions in the state, the second-highest rate among black students, the second-highest among students learning English and the third-highest among Latino students.

Elizabeth Winangun, the charter school’s director of external relations, said the mayoral academy suspended 14 percent of its students during the 2017-2018 school year.

“This [school] year,” she said, “we committed to significantly reducing that number. We put a plan of action in place, and I am happy to report that it is working. Year to date, our suspension rate is below 1 percent, an all-time low.”
