Mountainside High School
CEEB Code: 381293
Principal: Natalie Labossiere

School and Community:

Mountainside was established in 2017 and is the newest of our district’s comprehensive high schools. 

In the 2025-2026 school year we will serve approximately 1,800 students in grades 9-12.  Our first graduating class was in 2020, and we are proud to say that we currently have an on-time graduation rate of nearly 95%.  Our students identify with a variety of racial identities and backgrounds and speak 41 different languages.

Mountainside is an authorized International Baccalaureate (IB) Diploma Program and Middle Years Program school.

Academics:

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.  A half credit (.5) is granted for satisfactory completion of an 18-week course in the core classes for all grade levels and in elective courses for 10th-12th grade students.  Some of our 9th grade elective courses are offered in a unique wheel structure.  Each subject area in the wheel electives is taught for nine weeks and earns .25 credit.  All students can earn up to 3.5 credits per semester for a total of 7 credits per year.  

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.  Any score of 1.99 or below, will receive a grade of “I” (incomplete) or “N” (no grade) depending on the individual circumstances, and the teacher’s professional judgment.  When the average falls on a cut-off score (2.0, 3.0, 4.5 or 6.0) the higher grade is recommended.  A grade of “D” or above is considered a passing grade for satisfactory completion of a course.  

IB Diploma Program Information:

As an authorized IB Diploma Program school, we offer the following IB courses to students: IB Biology SL/HL, IB Design Technology, IB Environmental Systems and Societies SL, IB French SL/HL, IB Geography SL, IB Global Politics SL/HL, IB Language and Literature HL, IB Music/Band SL/HL, IB Music/Choir SL/HL, IB Math Analysis and Approaches SL/HL, IB Math Applications and Interpretations SL, IB Physics SL/HL, IB Spanish SL/HL, IB Theory of Knowledge, IB Visual Art SL/HL, and IB World Religions SL.  

IB Courses are 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 and all of our 11th grade students take a minimum of three IB courses.   Students are encouraged to explore as many additional IB courses as they wish to pursue and we offer them the option to test in none, some, or all of their IB courses.  We have 41 current 12th grade students who intend to complete the full IB Diploma process this year.
