Cambridge’s three charter schools are joining for the first time to host a charter school fair. It takes place Tuesday evening at the Cambridge Community Center.

It gives parents and others the chance to learn about charter schools in general and about Cambridge’s specifically:

bullet-gray-smallThe Benjamin Banneker Charter Public School in North Cambridge serves 340 students in grades Pre-K to 6 from Cambridge, Boston and beyond. Founded nearly 20 years ago, the Banneker is one of the oldest charter schools in the nation, and has become a leader in science, technology, engineering and math education at the elementary school level. The school boasts of its strong sense of community and the quality of its curriculum.

bullet-gray-smallThe Community Charter School of Cambridge near Kendall Square and MIT serves 360 students in grades 7 through 12 and is adding a sixth-grade class in the upcoming academic year. Opened in 2005, the school says its students take an academically rigorous, college preparatory curriculum that balances high expectations with a high level of individual support. Its 10th-graders have been achieving “outstanding” MCAS scores as a result, officials said, and all of its graduates have been admitted to college – more than 90 percent to four-year schools.

bullet-gray-smallProspect Hill Academy Charter School, on three campuses in Somerville and Cambridge, serves nearly 1,200 K-12 students from diverse racial, ethnic and economic backgrounds. The school was founded in 1996 with the mission to prepare each student for success in college, to inspire a lifelong love of learning and to foster responsible citizenship. The school said it was ranked among the top 2 percent of high schools by U.S. News & World Report and among the top 25 percent of state districts by the Department of Education, and that 95 percent of its graduates matriculate to four-year colleges.

This fair is scheduled for 6 p.m. Tuesday at the Cambridge Community Center, 5 Callender St., in the Riverside neighborhood between Central Square and Memorial Drive.
