Position Summary

Strive Charter School is seeking energetic, dependable, and student-centered Science Teaching Assistants to support Lead Science Teachers in implementing our Living Science Curriculum during the school day. Additional after-school and weekend hours may also be available based on program needs.

Living Science is an inquiry-based, Montessori-informed science program in which students learn through careful observation, hands-on investigation, experimentation, modeling, fieldwork, discussion, and environmental stewardship. Science Teaching Assistants help create a safe, engaging, organized, and welcoming learning environment where students can explore the natural world, ask questions, use scientific tools, collect evidence, and develop confidence as young scientists.

The Science Teaching Assistant works closely with the Lead Science Teacher to prepare materials, support science labs and small-group investigations, supervise students during field and outdoor experiences, reinforce science and safety routines, and maintain classroom materials and learning spaces.

The ideal candidate enjoys working with children, communicates effectively, takes initiative, is comfortable with hands-on and outdoor learning, and can maintain a positive and structured environment while encouraging curiosity and student independence.

Program Hours

Strive Charter School is open seven days a week from 7:00 a.m. to 7:00 p.m.

Employees will receive an assigned schedule based on program and staffing needs. Science Teaching Assistants should be prepared to support programming during the school day as well as assigned after-school, evening, or weekend activities when needed.
