school eventually housed grades 9–12 of Pembroke residents, while Kingston, Halifax and Plympton residents continued to attend at the original building. Silver Lake graduated its largest class, of 510 students, in 1981. Attendance peaked in 1980, when enrollment in the high school was 2100 students with just over 1000 students at the junior high. Subsequently, and throughout the 1980s, enrollment declined. In 1991, the region closed the junior high building, and converted the Pembroke campus to the junior high, while the Kingston campus once again became the sole high school campus, housing students from all four towns as it had prior to 1976. Attendance dropped from 2100 in 1980 to 1260 in 1993. Continued overcrowding in the school led Pembroke (with a population by 2000 half again what it was in 1970) to withdraw from the district and form its own independent school district in 2002; its students remained enrolled in Silver Lake until 2004. A new high school was constructed on the site of the original building, which opened in 2004. The school is one of the most expensive standing in Massachusetts and is adjacent to the district's middle school, the Silver Lake Middle School. The 1955 high school building stood until 2005 when it was torn down; however, the original football field, Sirrico Field, remains. The school was cited in Boston magazine as being one of the 2008 fifty top schools in eastern Massachusetts. Athletics The name for the Silver Lake teams is the Lakers. Tony Sirrico, who had taught and coached at Pembroke High School in the 1950s became the first athletic director at Silver Lake. He also coached football and baseball at Silver Lake. In 1955 Silver Lake was a Division III school in the South Shore Conference. In 1966 it moved up to Division II and joined the Old Colony League. In 1986 it moved to Division I. The school has a football program (1980 Division III Super Bowl Champions) and was regionally known for excelling in basketball (in which it won a state title in 1960, coached by future Boston Celtics assistant coach John Killilea), hockey (in which it reached the Division II Eastern Mass Finals in 1977) and soccer (in which it won a state title in 1988). In 2005, after the withdrawal of the town of Pembroke, Silver Lake began competing in Division II. The Lakers now compete in the Patriot League
