Students, parents, alumni, staffers and anyone else connected with West Junior High School’s past, present or future are invited to the school’s 50th anniversary celebration this Saturday.

The celebration will include an open house, tours, displays and punch and cake from 4:30 p.m. to 7 p.m. at the school, 2700 Harvard Road.

Visitors will be able to visit five “decade rooms,” spanning the ’60s, ’70s, ’80s, ’90s and ’00s with yearbooks, school newspapers, uniforms, trophies, theater props and other memorabilia from times gone by, as the community looks ahead to starting the next era: The 2011-12 year will mark the school’s first with grades 6-8, reopening and operating as West Middle School.

“We’ve been doing this for over 50 years,” said Jeff Harkin, assistant principal. “West will still be best.”

The public also is invited to attend the school’s Chorale Spring Show, with performances set for 6 p.m. and 8 p.m. Friday and Saturday. The fitting theme: “WJHS 50th Anniversary,” and tickets are available for sale in the school office.
