Where it is

The campus is on N. 128th Street in east Scottsdale, in the 85259 ZIP code. The school describes itself as being in close proximity to Desert Mountain High School, and its homepage names the Desert Mountain Learning Community, the district's grouping of schools in this part of Scottsdale. The front office is open 7:00 a.m. to 3:30 p.m. on school days.

About the school

Mountainside opened in 1991 and uses the tagline "Inspire. Learn. Lead." The biggest thing to know is that it is an IB World School. Every student in grades 6 to 8 takes part in the IB Middle Years Programme, which covers years 1 to 3 of the program. Years 4 and 5 continue at Desert Mountain High School, so students who stay on that path can keep the same framework into high school.

The MYP subject areas listed on the school site are:

  • Language and literature, and language acquisition, with French, Mandarin and Spanish offered
  • Individuals and societies, sciences and mathematics
  • Design, which includes STEM, computers and media
  • Arts, plus physical and health education
  • An 8th grade Community Project and service as action

The arts page lists band, choir, orchestra and strings, theatre and visual art as offerings. Clubs posted by the school include Drama Club, National Junior Honor Society, Science Olympiad, a before-school Jazz Band from November to April, and an after-school Robotics club. Sports listed include volleyball, baseball, basketball, soccer, softball, flag football, cross country, track and field, and spiritline. The school site also links to the district's before and after school care program and a summer camp; ask the district for current details on both.

Attendance boundaries and enrollment

SUSD assigns students to schools by home address, so the first step for any house is the district's middle school locator. Please confirm boundaries with the district. A home near Mountainside is not guaranteed to be assigned to it.

This matters more than usual right now. SUSD's Phase II school repurposing page says the approved plan closes Copper Ridge and Laguna Prep after the 2026-27 school year, and some of the boundary options it describes would assign additional neighborhoods to Mountainside for grades 6 to 8. The district says it will share specific school assignments after the Governing Board's decision, so check the locator and the district again before you buy.

For 2027-28, the school says regular and open enrollment begin November 2, 2026 at 8 a.m. Regular enrollment is for students in the school's boundary and asks for proof of residency, a birth certificate, current immunization records and online registration forms. Open enrollment is for students outside SUSD boundaries or in-district students who want a different school, and acceptance depends on grade-level and program capacity and meeting admission requirements. The school also offers optional campus tours.
