Assessment and Data Analysis
The Assessment and Program Evaluation Department at Tigard-Tualatin School District is responsible for facilitating the administration of standardized assessments and promoting the effective use of assessment data within the district. Assessments provide educators with measurable data of student performance on both behavioral and academic expectations. Such information can be used to evaluate student abilities, inform classroom instruction, and improve educational programs.

-
It is the process of using evidence to understand and improve student learning in academic programs. TTSD utilizes three types of assessments to accomplish this goal.
- The first is academic assessments where the student is tested on specific academic knowledge and skills. These assessments take the form of your traditional "test."
- For the second, we utilize student engagement data such as attendance rates, office discipline referrals, and course performance (class grades) to determine how/if the student is able to participate in the learning.
- The final assessment gages student perception. Students are surveyed on their experiences in school, with teachers, classmates, and the content of their lessons.
-
Academic Assessments
These assessments consist of those that we traditionally think of as assessment. They are tests that we give on student knowledge and skills in our different subject areas like science, English language arts, math, social studies, etc. Our department manages those standardized assessments mandated by the state as well as those we as a district use to monitor student growth on an interim basis throughout the year.

Oregon Statewide Assessment System (OSAS)

Pursuant to federal and state accountability requirements, Oregon public schools test students in English language arts and math in grades 3 through 8 & 11 and science in grades 5, 8, & 11.

IDEL, El Camino, and MAZE tests to measure students' skills which range from the awareness of letter sounds (Phonemic Awareness) and the ability to blend them (Nonsense Word Fluency) to speed and accuracy when reading aloud (Oral Reading Fluency). -

Student Engagement
Student engagement data consists of those data points we typically find on a report card. It includes not only course grades, but also a student's attendance rate and office discipline referrals, which are also included in most report cards. These data points together are a good indicator of a student's ability to engage/participate in class and the content.

-
Attendance
Showing up for the content, either in-person or virtually, is a necessary first step for engagement with and building understanding of that content.
-
Behavior
By tracking the number of office discipline referrals, we are able to better understand the climate and culture of the classroom/school in which the student engages with the content. This is especially true for students who are themselves referred to the office as it can result in loss of instructional time due to detention and/or suspension.
-
Course Performance
A student's course performance (class grades) is the final indicator determining their ability to engage with the material. After taking into account their attendance and behavior, course performance measures their ability to interact with content directly through their classwork.
-
Student Perception
How a student sees their own learning experience is a vital data point for understanding the context behind all the other data points. Do they feel safe in school and connected to their teachers and fellow students? How well are they able to access academic supports? What possible home issues might be occuring that affect their learning? The answers to these questions help us better understand the overall climate and culture of our schools.

TTSD Fall Opening Strong Survey
This survey is administered in partnership with our Student Services and Equity Departments. In the Fall of 2021-22, the district piloted an "Opening Strong" survey to gage student perception of their learning experience. Rather than being anonymous like most surveys, this survey was confidential. Student responses were collected by the district, but the students' school and/or teachers did not know how they answered individual questions. By making the survey confidential, we are able to learn how their perceptions affect their other indicators (academic and engagement). The district will be implementing the survey again this Fall.

Student Health Survey (SHS)
Oregon's Student Health Survey (SHS) is a collaborative effort with the Oregon Department of Education to improve the health and well-being of all Oregon students to help them succeed. The SHS is a comprehensive, school-based, anonymous and voluntary health survey of 6th, 8th and 11th graders. It is a key part of statewide efforts to help local schools and communities ensure that all Oregon youth are healthy and successful learners.

Student Educational Equity Development Survey (SEED)
Developed by the Oregon Department of Education and currently being piloted by multiple districts. This survey is expected to be required by the state no later than the 2023-24 school year. More information will be provided as the state prepares for full implementation.

-
Once assessments are administered and/or data is collected, the department works to analyze that data, integrate it into our reporting system, and provide meaningful and actionable results to our constituents. The department manages several long-term evaluation projects as well as responding to ad hoc requests as they come up.
-
ION
ION is a data analysis tool utilized by the district to combine our multiple assessments - academic, engagement, and perception - in as near real time as possible. Schools utilize ION to analyze data, determine action steps, implement strategies and/or interventions, and track results.

Strategic Plan Data Report (SPD)
The district Strategic Plan focuses on four cornerstones of success: student achievement, equity, talent, and climate/culture. Our department utilizes multiple data sources to track the impact of that plan on our school system.

Continuous Improvement Plan (CIP) Data Reports
Schools and districts in Oregon are called upon to engage in continuous improvement work to improve outcomes for students. The State CIP process requires districts to
- Determine what is working and what needs to change;
- Establish a process to engage stakeholders to effect change;
- Leverage effective practices to implement a plan;
- Use data to monitor and make timely adjustments to improve outcomes.
Our department provides quarterly reports for both our district as a whole and our individual schools to gauge the impact of their CIP.
