There are multiple elementary, middle, and high schools within the Alum Rock Union School District and Berryessa Union School District, so it's difficult to definitively state which school is the "best". Each school may have different strengths and areas of focus, and what is considered "best" can vary depending on individual criteria and preferences. Additionally, factors such as academic performance, extra-curricular activities, and overall school culture can change over time.
To determine which school might be the best fit for a particular student, it would be advisable to gather information about schools in the Alum Rock area, consider factors that are important to you (such as curriculum, facilities, student diversity, parent involvement), and potentially visit the schools of interest before making a decision.
