Bright Beginnings Preschool standards are measured by the quality of our staff.  Each teacher brings her own special skill and diverse background to the preschool program.  Every class has a lead teacher and assistant.  By maintaining the DCFS ratio of 1:10, our staff is able to provide children with a safe and stimulating environment.  Our preschool staff must maintain 15 hours of in-service in early childhood every year, and are certified in CPR, AED & First Aid.
