2020-2021 TCAP Participation Rate

After two unusual years in education, educators and families have the critical goal of measuring each student’s learning. Participation rates help show how well a school or district did in achieving that goal. The participation rates across student groups can help with interpreting the Achievement and Growth data from the 2020-2021 school year.

There are two ways to look at TCAP Participation rates: Hold Harmless Participation and Valid Score Rate. Hold Harmless Participation has been used in Tennessee for many years and was used for measuring participation to be held harmless provisions of PC 2 (further details for this participation can be found here and here). Valid Score Rate measures the percent of students who ultimately received proficiency scores for each exam (details on this can be found here). For most student groups, these two rates will be the same. But if these rates are different, they help in interpreting the student performance and student growth data.

These participation rates include all TCAP exams for grades 3 through 12. More details on which tests are used can be found here.

Hold Harmless Participation

Hold Harmless Participation is the percent of students recorded as at least attending each expected test.

Valid Score Rate

Valid Score Rate represents the percent of students who finished enough of each test to receive a valid score and measure their learning.

Hold Harmless Comparison by Entity

  • 80% Tennessee Threshold

  • 95% Federal Threshold

What does this mean?

This is the Hold Harmless Participation compared to the 80% participation goal, state, and/or district rates.

Why is this important?

This shows how successful a school or district was in encouraging families to show up for testing across student groups.

Valid Score Comparison by Entity

  • 80% Tennessee Threshold

  • 95% Federal Threshold

What does this mean?

This is the Valid Score Rate compared to the 80% goal, state, and/or district rates.

Why is this important?

If there are differences between Valid Score Rate and Hold Harmless Participation, students may have been marked as present for testing but did not do enough to get an accurate measure of their learning. Differences between this graph and the graph on the left help highlight where student groups might not be fully represented in achievement or growth results.
