Who We Are

Mission and Vision

YouthBASE equips children in K5-2nd grades and their families to build the child’s behavioral, academic, social and emotional competencies so they may succeed at school, home, and in the community.

We envision a community where all children succeed. Success to us means that children have age appropriate behavior and social/emotional capacities/opportunities and grade level academic proficiency to experience success at school, at home and in community.

  • Performing at or above grade level academically
  • Age appropriate behavior (respectful, polite, good communication skills)
  • Age appropriate social skills and ability to positively express emotion
  • Emotionally supportive environment
  • Strong families build strong children
