CRLS meaning in International ?

The Cambridge Rindge and Latin School, also known as CRLS or "Rindge," is a public high school in Cambridge, Massachusetts, United States. It is a part of the Cambridge Public School District. In 1977, two separate schools, the Rindge Technical School and Cambridge High and Latin School, merged to form the Cambridge Rindge and Latin School. The newly built high school at the time increased its capacity to more than 2,000 students from all four grades.

The school is divided into 'Learning Communities.' The Learning Communities are called C, R, L, and S. Until June 2000, the subdivisions were called Houses: Pilot, Fundamental, House A, Academy, Leadership, and the Rindge School of Technical Arts or RSTA. In 1990, RSTA became a "house" within the main CRLS school. The "Houses" then temporarily became "Schools" (called schools 1/2/3/4/5). In 2004 the schools transitioned to become "Learning Communities" C (formerly school 1), R(formerly school 2), L(formerly school 3), and S(formerly school 5).

The High School Extension Program, at the site of the old Longfellow School, just down Broadway, offers a nontraditional approach to the high school learning process, handling only 60–100 students at a time. In 2009 and 2010, the building became a temporary freshman academy to accommodate renovations.

CRLS is noted for its diversity.

Beginning in 2003, the City of Cambridge mobilized an ambitious plan to renovate the high school. The project was claimed to be "the first major renovation and refurbishing of the 35-year-old [sic] high school building." The project continued to be pushed back, due to state funding issues and other obstructions along the way. In 2006, the state announced a return in funding, and by the Spring 2007 the School Committee started looking at wider ranging renovations for the building. The renovations were undertaken in 2009-2011.
