TNReady Data Explained

TNReady Data Explained

ACS Families,

I hope you’re having a great start to the new school year! As many of you are aware, today the Tennessee Department of Education released data from the 2018-2019 TNReady state tests.

I’m thrilled to report that for the second year in a row, both Arlington & Donelson Elementary Schools are Reward Schools, which is the highest designation a school can receive in the state. Additionally, as a district, ACS has been named Advancing – the 2ndhighest achievement a district can earn. This year, our district’s score was 2.9, up from last year’s 2.61. ACS was only 0.2 points from earning Exemplary status.

When rating each school, the state considers two factors: Achievement and Growth. I want to briefly explain ACS’ results and what they mean for each school.

As mentioned earlier, AES and DES are Reward Schools and earned the top score in terms of both Achievement and Growth.

In terms of Achievement, which means students are on track or mastering state standards, ACS Grades 3-5 (AES and DES) ranked 2ndin the state, Grades 6-8 (Arlington Middle School) ranked 7th, and Grades 9-12 (Arlington High School) ranked 14th. Our students continue to perform with the best districts across the state.

Another factor the state looks at is Growth, also known as TVAAS. This measures student growth year over year, regardless of whether the student is proficient on the state assessment. In calculating a TVAAS score, a student’s performance is compared to the performance of his or her peers who have performed similarly on past assessments.

In terms of Growth, both AES and DES scored a Level 5, however, both the middle and high schools scored a 1 for overall growth.

These four scores calculated together led to the District scoring an overall Level 1. This does not sum up our students’ success, however. They continue to grow and compete on the state level. Our students grew in many areas, including Algebra 1, Algebra II, US History and Social Studies (see the chart below for a full breakdown).

As we continue to comb the data that was used to calculate this overall score, we have identified some areas that have overshadowed the large number of subjects that met or exceeded the growth standard. Additionally, although not included in the TVAAS Growth score, our students showed significant growth on the ACT, scoring a Level 5 composite.

So what are we doing to move our district forward?

Areas that scored under a 3 have already begun the work of addressing the fidelity of instruction to the state standards as well as aligning new resources being implemented this school year. Up until this year, ACS has been a Level 5, and we have no hesitation in our ability to return to that level.

As you can see in this letter, we have much to celebrate as we continue to perform with the top of the state in all grade bands for academic achievement, as well as having two of the four schools named Reward schools.

Thank you for your continued support of Arlington Community Schools!
