  • Note: This content is under review
  • Start the leveled literacy intervention as early as possible during the school year to provide the full 14 weeks of education.
  • Frequent trainings and integration of trainers with school administration help maintain program fidelity.
  • Program should be administered 30-45 minutes per day, 5 days per week, with the recommended group size.
  • Without appropriate staffing and small group approach, participants will not reap the full benefits of the program.
