The time right after Labor Day is great for giving your Sunday School a boost. Since Sunday School attendance is one of the best ways to predict the long-range health of your congregation, this is really important. If you can't remember, then you can be sure it's time for another one. Plan carefully, and receive six week commitments in advance for a few core people. Of course, invite people who are not currently active in Sunday School as well.
Newcomers are much less likely to join an established class than a new class.
Provide An Alternative. Holidays are great opportunities for local churches to impact the community, and alternative activities and celebrations are a good way to approach persons who are not yet churched. Even if it is, local churches which offer fun and safe alternatives are popular with both children and parents. You will be amazed at how many children from the community will flock to your church, so plan carefully and publicize well. Be sure to get registration information, and follow-up on children and families who have no church home.
