API stands for Academic Performance Index. California has used this index to measure schools for the past decade. Granite Hills has embraced a culture of continuous improvement. We never stop working at getting better.
Over the last 10 years, Granite Hills High School has seen its API increase by 89 points. During this time, teachers have--among other things--collaborated with each other in professional learning communities, diversified their instruction, maintained a focus on California state content standards and used assessments to inform their instruction.
