The Sage Hill School application page shows that the 2027-28 application for grades 7 through 12 opened September 1, 2026, that applicants must take the ISEE or SSAT, and that scores must reach the school by the January 31, 2027 application deadline. The events page lists campus tours on October 19 and December 7, a parent coffee panel on October 26, and Shadow Days from October through February. The school sits in Newport Coast, next to Irvine, and is among the schools Irvine families compare most often when applying to private high schools.

What to Do Now About the Sage Hill School Application
Settle the test first. The ISEE may be taken once per testing season while the SSAT may be taken several times a year; the rules are in ISEE Once per Season, SSAT Several Times a Year. Scores must arrive by January 31, so fall or winter registrations need to be made early. ISEE levels and preparation are covered at ISEE Prep.
Register early for the October 19 tour and the October 26 panel. Both have limited seating; families who want the student to experience a school day should submit the application and then select a Shadow Day from the checklist.
Families applying for aid should align the two deadlines. Both the application and the Clarity aid application close January 31, and aid applications completed after that date go to the wait pool. The school’s curriculum and college outcomes are covered in the Sage Hill School Admissions and College Guide; the comparison across Orange County private high schools is in the EDUBUS Orange County Private High School Guide.
