Touching base on the Regulations, and EEC's Sample Progress Report...

Early education and out of school time providers are experienced observers of children, and can offer valuable information to parents about their children's development. Early education and care and out of school time programs provide children with different opportunities than home or school to demonstrate new skills, either individually or in groups. Sharing your observations with parents may give them new insights into their child.

The new regulations expand the current Group Child Care requirement for progress reports to include Family Child Care and School Age Child Care.

Progress reports must be prepared:

•every 3 months for infants and children with special needs;
•every 6 months for toddlers and preschoolers; and
•at least annually at the midpoint of the child's program year for school age children.
Progress reports for children younger than school age must address all developmental domains, including cognitive, social/emotional, language, fine and gross motor, and life skills. Progress reports for school age children can be limited to the child's growth and development within the context of the program's statement of purpose

Are parent signatures required on the new progress reports? How do I know parents will even read them? What if they disagree with what I've written?
You must offer parents an opportunity to meet with you to discuss their child's progress, and let them know you value their perspective on their child's development but you do not need a parent signature. You must maintain a copy of the child's progress report in the child's file. Most parents are very interested in how their children are progressing and in seeing their "work", and will look forward to your reports.

The technical assistance materials located at http://www.eec.state.ma.us/licensingRegulations.aspx includes information about how to write reports in a factual, objective, positive way, and how to share information with parents.
