DUBLIN — Saying Dublin needs another comprehensive high school, a group of parents hopes to open a charter school for high school-age students in fall 2012.

While the Web site for the proposed Tassajara Preparatory High School notes that Dublin High School, the city’s sole comprehensive public high school, is on the west side of town — and some East Dublin residents have expressed concerns about their proximity to Dublin High — the parents group’s leader downplayed the geography issue.

“It doesn’t matter to me, east or west,” said Rully Kusuma, president of the group, called the Dublin Learning Corporation.

Yet the group’s Web site says its vision is an East Dublin location, and a news release announcing the effort quotes Kusuma as saying organizers want to create a sense of community “while eliminating the need for thousands of daily crosstown car trips to the only high school currently available, which is on the west side of town.”

Three town hall meetings are scheduled to get community input on the charter school idea, with the first being 7 p.m. Oct. 20 at the Dublin Library, 200 Civic Plaza.

Kusuma said plans are preliminary, but the charter school would focus on college prep. He also said organizers do not have a problem or concerns with the Dublin school district — and even hope for some collaboration — but his group wants to offer parents another option.
