Begin by reviewing school performance data from the California School Dashboard and the California Department of Education, which provide metrics like test scores, graduation rates, and college-readiness indicators. Compare these with independent rating sites such as GreatSchools or Niche for additional context and parent reviews. Focus on schools in reputable districts like Walnut Valley Unified School District, which serves much of Diamond Bar, and verify each school’s recent performance trends rather than relying solely on one year of data or a single rating source.

In addition to test scores, evaluate class sizes, student-to-teacher ratios, campus safety, and the availability of advanced placement (AP), honors, and elective courses that match your student’s interests. Consider the strength of extracurricular programs such as athletics, visual and performing arts, STEM clubs, and academic competitions. Review the school’s support services, including counseling, special education, English language development, and college and career guidance. Visiting campuses, attending open houses, and speaking with administrators, teachers, and current parents can give you a clearer picture of the school’s culture, leadership, and communication style.

Many families look for homes within the boundaries of Walnut Valley Unified School District, as it is frequently recognized for high-performing schools that serve portions of Diamond Bar. Neighborhoods zoned for well-regarded elementary and high schools often have strong residential demand, which can influence home prices and competition. Because attendance zones can change over time, confirm the current school assignments for any specific address using the district’s boundary maps or by contacting the district office directly before making housing decisions. It is also wise to verify whether a property is within a preferred school’s attendance area or subject to overflow policies or lotteries.

Start by identifying your address and using the school locator or boundary map on the website of the district that serves your area, such as Walnut Valley Unified School District or Pomona Unified School District, depending on the specific location in Diamond Bar. These tools typically allow you to enter your street address to view assigned elementary, middle, and high schools. After checking online, call the district’s enrollment or student services department to confirm the information and ask about any recent boundary changes, special program placements, or capacity issues that might affect your assignment. When you enroll, the district or school office will provide final confirmation of your child’s school placement and any required documentation.

If your preferred school differs from your assigned school, inquire about intra-district or inter-district transfer options, which may allow you to apply for another public school within the same district or a neighboring district, subject to space and eligibility criteria. Some districts also offer specialized magnet, dual-language, or academy programs with separate application processes and deadlines, so review those requirements early. If you are considering private or charter schools in or near Diamond Bar, contact each school directly to learn about admissions timelines, entrance assessments, tuition or fees, and financial aid options. Keep copies of all correspondence, submit applications before published deadlines, and confirm acceptance in writing to secure your child’s place.
