Datamap: How to access EVAAS value added projection scores

Value added OST target scaled scores are available in DataMap for these tests:
ELA grades 5,6,7,8, and HS ELA 2.
Math grades 5,6,7,8, Integrated 1 and Integrated 2.
Science grades 5 and 8.

This article will begin with instructions for accessing target scores, followed by explanatory information for the curious.

OST - Ohio's State Tests
Value Added - a measure of whether the student's OST performance indicates that the student as achieved a year's growth. The state measures a student's OST performance as a percentile (how the student scored compared to all other students on that particular test), and uses years of that data to project where the student should score if the student grows like students who scored similarly. In layman's terms, the state has tens of thousands of scores just like a particular student's scores, and they know how those students typically performed the following year, and they use that data to give your student a target percentile for the coming year.

Accessing Value Added OST target scaled scores

Individual student target scores

Go to any student's roadmap screen (

The student will have a target scaled score for each test where the data could be harvested (information on that process can be found below).

For the above student, you can see the 2020-21 OST scaled score for each subject, followed by the Restart Readiness scaled score, and finally the VA target scaled score.

List of student target scores

You can also use DataMap's multiple measures tool to view a list of your students' target scores. You can even add other assessment data you'd like to see next to target scores.

You will set your search parameters on the left, then click the find button at the bottom left. If you don't get exactly what you wanted, take another look at your search parameters. There are a LOT of options, which makes this feature both powerful and tricky to use.

You must first select a subject at the top left. If you are looking for ELA data, always choose English\Reading\Writing.

Next you will add in the data points you'd like to see.  This is where it can get complicated, but also where the power of the Multiple Measures feature lies.

First, the simplest search: a list of student value added projections.

Choose a subject. Select a VA target subject from the District Assessments list. Add a grade level, teacher, or even a course/section if desired. Click the find button when ready.

Next, a more advanced search showing other assessments and scores.

Projected scores alone aren't as helpful as seeing all of the student's data in line.  We want to be able to assess the student's progress toward their target score, so we want to see scores from other assessments.

We can add data points as we go, DataMap keeps your selections when you click find. This means you can add and remove items until you have what you want.

Select OST and 2020-2021 from the State Assessments section.

Select MAP from the Third Party Assessments list.

We have asked DataMap for lots of data now.
Last year's OST score, this year's MAP scores, and the state's value added target score for ELA 5.
Click find.

DataMap delivers! Remember that you can refine your search criteria by changing selections on the left and then clicking find again. 
This process can take a bit of practice, but you will quickly figure out where to look for the data you want. If you need help finding something or are struggling with searching, just ask! Mark will walk you through it, or load the missing data if it does not exist.

Explanation of data

There is a lot of data that can be downloaded from various ODE reporting sites.
EVAAS / ODE give us...
1. Projected student performance for the current year's OST assessments in the form of percentiles. These percentiles are the measure used to determine if a student meets Value Added.  Taken together, these results determine district and teacher value added ratings.
They provide projections for the following assessments:
ELA grades 5,6,7,8, and HS ELA 2.
Math grades 5,6,7,8, Integrated 1 and Integrated 2.
Science grades 5 and 8.

On their own, these projections tell us how a student is expected to perform relative to his/her peers if he/she is to show a year's growth (meet VA).

  1. Diagnostic results from 2020-2021 in the form of State Student ID numbers and percentile scores.

This data tells us how a student (really an SSID) performed on last year's test relative to his/her peers.

  1. 2020-2021 OST results, including scaled scores.

We want to turn 2021-2022 student projections into actionable data by turning target percentiles into target scaled scores.

We do this by gathering all of last year's percentile data (number 2 above) and connecting it with last year's OST results (number 3 above) to create a table of real world percentile and scaled score results.  

Now we have the percentile and corresponding scaled scores for each of the assessments listed above.

Finally, we connect this year's projected percentiles to last year's scores table to provide teachers with VA target scaled scores for individual students.](
