Current enrollment is 750 students in pre-kindergarten through grade 12.

When the new fall semester begins Thursday, students, parents and the public may join the celebration to bless a new library and six-classroom building that positions the school to almost double the size of its middle school class in the next year.

Thursday's program is scheduled to begin at 10:30 a.m. and will include performances by Le Jardin students, plus the presentation of $7 million in checks from the Harold K.L. Castle Foundation, the Charles B. Wang Foundation, and the school's own trustees.

The new facilities are the first to be completed for the $21.4 million campus expansion that moves into the second phase this week when grading for a $9 million gymnasium is launched.

The second phase will also include an administration building and 12 more classrooms.

To date fund-raising has reached $9 million and headmaster Adrian Allan hopes the goal will be reached in another three years.

The school is also in the process of doubling its acreage to almost 50 acres, as attorneys work with a new donor who is hoping to give the school an additional 20 acres along the Quarry Road.
