Connecticut's State-Based Assessments:Why They Exist, How Districts Use Them, and What Parents Can Do

Each spring, students across Connecticut participate in statewide assessments designed to measure academic progress in English language arts and mathematics. 

For many families, the results arrive in the fall with limited context. 

To become an informed advocate for your child, you’ll need to understand what these assessments are intended to measure, how school districts use the data and what parents can do with the information. Below, we’ll dive into all three.

Why Does Connecticut Require State-Based Assessments?

The primary purpose of state-based assessments is to provide a consistent, comparable measure of student achievement across all schools and districts. 

According to Connecticut's Assessment FAQ published by ReadyCT, standardized testing gives schools, districts, policymakers, and families a statistically accurate picture of how students are performing relative to grade-level expectations statewide. 

Without this consistent measure, gaps in achievement among different groups of students would be difficult to identify and address.

Connecticut uses the Smarter Balanced Assessment (SBAC) for students in grades 3 through 8, measuring proficiency in English language arts and mathematics. 

In 11th grade, students take the Connecticut SAT School Day, which assesses college and career readiness. 

Both tests are aligned to Connecticut Core Standards. 

According to the Connecticut General Assembly, these summative assessments are administered at the end of each school year and results are reported across four performance levels, ranging from Level 1, which indicates a student has not yet met the standard, to Level 4, which indicates a student exceeds it.

These assessments also fulfill a federal requirement. Under the Every Student Succeeds Act (ESSA), states must assess every student annually  in grades 3 through. Additionally, states must assess high schoolers once in reading and mathematics. This requirement exists to ensure that all students, including those with disabilities, English learners, and economically disadvantaged students, are being measured against the same academic standards and that schools are held accountable for the progress of every subgroup.

What Do Districts Do With the Scores?

School districts use SBAC results as one component of a broader accountability system. According to the Connecticut State Department of Education, assessment data informs Connecticut's Next Generation Accountability System, which evaluates schools and districts across twelve indicators. Test scores contribute to a district's Connecticut Performance Index (CPI), which tracks average achievement and growth over time and is used to identify schools that may need additional support or resources.

At the district level, SBAC data is used to evaluate curriculum effectiveness, identify instructional gaps, allocate professional development resources, and determine which student subgroups may need additional support. 


Districts are required to disaggregate data by student group, meaning scores are reported separately for students with disabilities, English learners, economically disadvantaged students, and students of different racial and ethnic backgrounds. 


This disaggregation is what makes it possible to see whether certain groups of students are being underserved even when overall district averages look strong.

One Town, Many Stories: Old Saybrook’s Report Card

Old Saybrook's district-level data illustrates this clearly. According to Public School Review, the district's overall reading proficiency rate of 66 percent exceeds the Connecticut state average of 51 percent, and its math proficiency of 54 percent exceeds the state average of 42 percent. The district ranks 70th out of 197 Connecticut school districts overall.
