The Ohio Department of Education was tasked with producing a report detailing the amount of testing being performed in K-12 public schools. You can read the report itself, below.
The report find the following: Total Testing Time for the Average Student in a School Year, in Hours
| Kindergarten | 11.3 |
| 1 | 11.6 |
| 2 | 13.6 |
| 3 | 28 |
| 4 | 24 |
| 5 | 22.6 |
| 6 | 22.3 |
| 7 | 21.1 |
| 8 | 23 |
| 9 | 20.4 |
| 10 | 28.4 |
| 11 | 18.9 |
| 12 | 12.2 |
| Total | 257.4 |
| Average | 19.8 |
That's a lot of testing, and is not fully comprehensive as the report notes.
ODE goes on to provide 8 action steps being taken, and ends with a number of recommendations, including
This report includes a comprehensive package of legislative recommendations to shorten the amount of time students spend taking tests. These recommendations place limits on the overall time students spend taking tests each year, eliminate unnecessary tests and modify the Ohio Teacher Evaluation System. The following recommendations are contingent on each other and would require implementation as a comprehensive set of reforms. If this package of recommendations is adopted, the state can reduce the amount of time students are taking tests by nearly 20 percent.
A clear admission that the testing regime in Ohio has gotten out of hand by at least 20%
To get there ODE lays out the following recommendations
Recommendation 1: Limit the amount of time a student takes tests at the state and district levels to 2 percent of the school year, and limit the amount of time spent practicing for tests to 1 percent of the school year. These limits will encourage the state and districts to prioritize testing and guarantee to students and parents that the vast majority of time in the classroom will focus on instruction, not testing.[...]
Recommendation 2: Eliminate the fall third-grade reading test and administer the test in the spring. Students who do not reach the required promotion score on the spring test will have a second opportunity to take the test in the summer.
[...]
Recommendation 3: Eliminate the state’s requirement that districts give mathematics and writing diagnostic tests to students in first grade through third grades.
[...]
Recommendation 4: Eliminate the use of student learning objective tests as part of the teacher evaluation system for grades pre-K to 3 and for teachers teaching in non-core subject areas in grades 4-12. The core areas are English language arts, mathematics, science and social studies. Teachers teaching in grades and subject areas in which student learning objectives are no longer permitted will demonstrate student growth through the expanded use of shared attribution, although at a reduced level overall. In cases where shared attribution isn’t possible, the department will provide guidance on alternative ways of measuring growth.
That last recommendation is a huge admission. Teachers and administrators have been hugely burdened developing and deploying SLO's and students have received little to no benefit from them. Here's the full report
