In addition, IDEA teachers set ambitious goals for student achievement and invest students and families in accomplishing them; create a powerful learning environment; plan and deliver purposeful, rigorous instruction; assess for mastery and track student progress toward goals; analyze data to intervene and adjust instruction; and seek excellence as an educator and an IDEA team member. Since 2000, IDEA Public Schools has grown from a small school with 150 students to a multi-state network of tuition-free, Pre-K-12 public charter schools.
