NTLA provides a rigorous curriculum for students. What exactly does that mean?

NTLA’s curriculum is designed to challenge students as they advance so it is possible for students to receive instruction above grade level to meet their needs. This advanced curriculum is designed by teachers to meet the needs of bright and gifted students. If a student has mastered all concepts in their grade level, they are provided instruction on the next grade level. NTLA uses a project-based curriculum which allows for teachers to continually assess and determine appropriate curriculum for each student. With class sizes no larger than 12, students have the benefit of individualized instruction and the freedom to learn at an advanced level.
