AgendaIntended Audience: Superintendents, Principals,
Leadership Teams, Success Coaches, and Educational Service District Leaders
Before beginning your review of these data, please reflect on your preliminary thoughts aboutstudents’ growth in your school.
One or more of the following thought-starters may be helpful.
– I assume…– I predict…– I wonder…– My questions/expectations are influenced by…

Action-Planning Process
• Section 2 of the Student Performance data in the Comprehensive Data Package and Services
Median Student Growth Analysis
• Student Growth Percentile or SGP: Describes a student’s growth compared to other students with similar prior test scores (“academic peers”)– E.g. Student-A: SGP=64 and Student-B: SGP=37
• Compared with students with similar past scores, Student-A grew more than 64% of the students in the state
• Compared with students with similar past scores, Student-B grew more than 37 percent of the students (or 63% of the students grew more than Student-B).
Student Growth Percentile - Refresher
• The Median (middle) of all students in your school at this grade level and content area
• Summarizes SGPs by district, school, grade level, etc.• E.g. Consider a school with 7 students in a grade

• Data are missing for MSP, HSPE, and EOC if…– Number of students assessed is < 10– Data are suppressed (“Enhanced Suppression”). In
July 2014, OSPI implemented a process to suppress data in certain cases even if count is > 10 students.
• Schools participating in the Smarter Balanced Assessment pilot testing in spring of 2014 won’t have MSP data in Reading and Math for grades 3-8.
“Missing data” in Charts
School’s data are missing for the entire subgroup; school probably has less than 10 students in each year.

Data are missing for 2011 and 2012 in the ELL group; school probably had less than 10 students in those years and population is now growing.
Missing Data Example: Data for Some Years
• Look at the top charts on each page of your report.
• Across the 4 years, do you see improvement? Declines in the data? Or are data staying flat?
• Are there differences between Reading and Math?
• What else do you need to know?
Pause and Reflect #2
• Strong (positive) improvement over time

• ALL STUDENTS chart shows acceptable growth (around 50 median SGP)
• ELLs show strong improvement in growth; this implies significant gap closure since they show higher growth.
All Students ELLs
• Look within each page of your report.
• What evidence do you see of gaps closing in your school?
• What else do you need to know?
Pause and Reflect #3
TriangulationSection 1: ProficiencyAre students getting to proficiency? Are we shrinking the percentage at Level-1?
Section 2: GrowthAre students growing? Are ELL, SWD, or Low-income subgroups catching up?
Section 3: ELLAre ELLs reaching English proficiency? What do we see with Former-ELLs?
Data around:– School and district strengths– Evidence-based programs and
services– Barriers
