About Our SchoolCentennial Elementary Entrance

Patrick Murphy, Superintendent

Shannon Ritter, Principal


Centennial Elementary School first opened its doors in 1989. Located in the southeast corner of Olympia, we serve students in grades kindergarten through 5th grade.

In September of 2018, a two-story intermediate building was completed and is home to our 4th and 5th grade students. The main building modernization was completed in January of 2020. The original footprint for the school remains the same with the addition of a second gym, a new entrance to the building, a re-designed drop-off area and parking lot. The three main pod areas were restructured to allow for small group work. The library received updates as well in order to better serve the needs of our students. The changes to the library include an enhanced focus on STEAM (Science, Technology, Engineering, Art and Mathematics). Additionally, a space dedicated as an Art Studio was added.

Our closely-knit community takes great pride in Centennial Elementary, which is well known for its parent involvement, academic rigor, music, PE, Art and Library programs, high volunteer rates and an experienced, talented and caring staff. The mission statement of Centennial Elementary School is to ensure high levels of learning for all. Our vision is to strive to promote a curiosity for learning. All staff members work collaboratively to provide meaningful learning opportunities for all students, with an emphasis on academic achievement and social/emotional growth.

Community members and parents are encouraged to come in and lend a hand. Parents may become involved with the school through volunteering or by joining the active Booster Club. A strong partnership with the families and community enhances the academic and social opportunities for students at Centennial.

Measures of Academic Progress (MAP)

MAP is a district assessment that measures a student's developing skills through a series of questions that adapt to the child’s level of learning. Research on MAP indicates the results are highly accurate. The results help teachers measure growth and determine whether a student may need more support or more challenge.


What is the Rasch UnIT (RIT) scale?

When students finish their MAP Growth test, they receive a number called an RIT score for each area they are tested in (reading, language usage, math, or science). This score represents a student’s achievement level at any given moment and helps measure their academic growth over time. The RIT scale is a stable scale, like feet and inches, that accurately measures student performance, regardless of age, grades, or grade level. Like marking height on a growth chart, and being able to see how tall your child is at various points in time, you can also see how much they have grown between tests.

The higher the RIT score, the more achievement the student has in the subject. The student's percentile ranking and conditional growth percentile can show how much the student has achieved in comparison with their peers. You can also refer to the Comparative Data to Inform Instructional Decisions to understand how students are performing relative to other students in the same grade level according to our national norms.
