🏆 IUSD ranks No. 1 in Math, Science and English Language Arts/Literacy (ELA) for the 10th consecutive year among districts serving 35,000 or more students, according to results from the California Assessment of Student Performance and Progress (CAASPP)! 📚🔬➗
📊 IUSD students continue to outperform state and county averages by significant margins! Here are some highlights:
In 2026, the percentage of IUSD students scoring proficient or above exceeded statewide rates by:
🔹 Math: 32 percentage points
🔹 Science: 29 percentage points
🔹 ELA: 25 percentage points
📈 More Students. Sustained Excellence. Over the past decade, IUSD has maintained high academic achievement while welcoming more than 7,000 additional students and serving a growing number of students requiring additional learning supports.
💙 What drives this success? Highly trained, dedicated teachers and staff who provide top-tier instruction, regularly assess student progress and deliver targeted academic interventions to meet students where they are. Together with our hardworking students and supportive families, we’re helping students succeed and prepare for college, career and life. 😃❤️
📚 Beyond the Test Scores: CAASPP results provide valuable insights into student learning, but they are just one measure of achievement and don’t capture the full range of students’ knowledge, skills and abilities.
👏 Congratulations to our IUSD community!
