Every day of the week, Monday through Friday, we run a variety of STEAM afternoon programs in Science, Creativity and Leadership. Classes  are open to all ages unless otherwise noted, and meet once a week, from 3:30 p.m. – 5:30 p.m., for 11-12 weeks (unless there is a holiday.) We divide the school year into trimesters, so students enroll in a particular enrichment program for one trimester at a time.

  • Fall:       September 6 – November 22, 2016
  • Winter:  November 29, 2016 – March 10, 2017
  • Spring:  March 13, 2017 – June 9, 2017


The cost for our afternoon programs is $30 per day per child. 10 week classes are $300, 11 week classes are $330, and 12 week classes are $360 per trimester. There is one exception: Please note that Science Lab programs are intensive, specialty offerings limited to six students, and priced differently ($870 – $950 per trimester, for details, see the registration form above.)


A bus service will be available for an additional fee to take students to various surrounding towns after our enrichment programs. The bus will depart Acera at 5:35 pm and service the following:

1. Winchester 5:45 pm, Westland @ High Street
2. Arlington 6:00 pm, McClennen Park
