Maybe the test of how well a program works is when its graduates volunteer to come back for another year. That certainly is the case for many of those who graduated from the AmeriCorps Central Valley Communities for Children program on August 26 at the Bakersfield City School District Auditorium. "All the hard work was well worth it," said Dorothy Belk, who spent her year with AmeriCorps tutoring children at Fremont School in Bakersfield. "I learned a lot this year, and I've enjoyed the children so much. That's why I'm coming back for a second year."
