Mountainside High School
CEEB Code: 381293
Principal: Natalie Labossiere


Mountainside High School was established in 2017.  It is a comprehensive high school serving students in the Beaverton School District.  During its initial year of operation, the school opened with 930 students in grades 9 and 10; for the 2018-2019 school year, we served nearly 1450 students in grades 9-11. Approximately 1,700 students currently attend Mountainside and we are accredited by AdvancED and the Oregon State Department of Education.

While the building is new, our community is long established with a legacy of rigorous academics, robust elective offerings, and substantial college and career preparation.  Mountainside is built upon that solid foundation and is an authorized International Baccalaureate (IB) Middle Years Program (MYP) school and IB Diploma Program (DP) school.  We also offer students courses in five career pathways with state-of-the-art Career Technical Education (CTE) facilities, and all students complete a .5 Career Education credit that provides them with the practical skills to succeed after high school.  


Mountainside’s classes are offered in a 7-period rotating block schedule over the course of two 18-week semesters.  Class periods are 90 minutes long.   Our students are assessed on a 1-8 grading scale and those grades are converted to traditional letter grades on report cards, and students’ official transcripts.  The grades are converted as follows: A= 8.0- 6.0, B=6.0-4.5, C= 4.5-3.0, D= 3.0-2.0; F= 2.0 and below.  When the average falls on a cut-off score (2.0, 3.0, 4.5 or 6.0) the higher grade will be recommended.  A grade of “D” or above is considered a passing grade for satisfactory completion of a course.  

A half credit (.5) is granted for satisfactory completion of a course over a semester in the core classes for all grade levels and in elective courses for 10th and 11th grade students.  Our 9th-grade elective courses are offered in a unique wheel structure.  Each subject area in the wheels is taught for 9 weeks and earns .25 credit.  This structure allows 9th grade students to explore up to 8 elective subject areas.  All students may earn up to 3.5 credits per semester for 7 credits per year.  Please see our online Academic Planning Guide for further details.

As an authorized IB Diploma Program school, we now offer the following IB courses to students:
IB Biology HL 1, IB Physics HL 1, IB Theory of Knowledge 1, IB Art HL 1, IB Music/Band HL 1, IB Music/Percussion 1, IB English HL 1, IB Math SL 1, IB Math HL 1, IB Global Politics SL 1, IB French SL 1, and IB Spanish SL 1.  IB Courses will be noted on the students’ transcripts by course title and with an “I” showing that the course is eligible for a weighted grade.  The Beaverton School District weighted grade policy states that the grades of A, B, and C will be weighted with an extra point (A=5, B=4, C=3) for class rank, and a weighted cumulative GPA listed on the students’ transcript.

Mountainside is an “IB for All”  school.  All of our juniors will choose an IB course in their standard junior Social Science, English and Math courses.  Additionally, students are encouraged to explore as many of the IB courses as they wish to pursue, and we offer them the option to test in none, some, or all of their IB courses.  Every year, we have over 50 students who complete the full IB Diploma process.

We are also an AVID Schoolwide high school.  Our students have access to AVID strategies across the curriculum to improve skills and college-readiness for all students.  Approximately 100 students are members of our AVID elective courses which specifically support first-generation, and/or underrepresented students to maximize their potential and preparedness for college options after high school.


Mountainside High School students must complete 24 credits in the following areas for graduation: 4 Language Arts, 3 Math, 3 Social Science, 3 Lab Sciences, 1 Health, 1 PE, 3 Applied Arts, Fine Arts, World Language or Business Education, .5 Career Education, and 5.5 Electives. 

Additionally, students must pass State of Oregon exams in reading, writing and math. They must also complete 40 hours of Community Service, 4 Career Related Learning Experiences, a Senior Capstone Project and an identified Career Pathway.
