From Route 2 in the Ayer area, go east toward Boston.
From Route 2 in the Arlington area, go west toward Concord.
Take the exit for Rte 27, Acton. Go off the ramp, following the signs toward Acton and Littleton, Rte. 119.
Proceed along Route 27, crossing Route 119, until you get to the lights at the intersection of Route 27 and Route 225. (This takes about 6-7 minutes from when you got off Rte 2) Take a right at that light.
Continue along Rte 225 (about 5 minutes) until you come to a stop sign.
Begin to go straight ahead at the stop sign. Ahead of you you will see a hill going off to the right - this is School Street. Do not go around the little rotary - stay to the right of it and take the right to go up School Street.
As you go up School Street you’ll see (right away) a white church on the left, at the corner of Church street. Take a left onto Church Street, then your first (almost immediate) right into the school’s parking lot.
Park your car in this lot, then proceed up the stairs, cross the bus plaza and go up the next set of stairs. The Spalding Building entrance is ahead of you. Go to the Main Office, which is the first down the walkway, to sign in.
