Data Questions

What is meant by standard scores?

Standard scores, sometimes called "Z" scores, are a way to measure differences.   The returned value takes into consideration the typical score as well as the number of available scores and how much those scores vary.  A positive score means the program's average score is above the typical average score.  A score outside of 1 or -1 means the program scored at least one standard deviation away from the typical program's score.   

Why report WEST-E scaled scores rather than pass/fail?

Like most states, all new teachers in Washington must pass a content knowledge assessment (WEST-E).  Because of this policy there is no difference in a program completer pass/fail rates (all 100%).  However, there are differences between the mean scores of completers by program.  There is empirical evidence suggesting content knowledge assessment scores relate to how teachers perform in the classroom.  The information shown in the application takes average of a program's past three year's results and compares against all programs that have at least 8 completers with test results.  

Studies and Reports

  • "There is a clear upward trend between teacher licensure performance and student achievement."
    Everyone’s Doing It, but What Does Teacher Testing Tell Us about Teacher Effectiveness?
    Dan Goldhaber

  • "The results for math achievement are quite striking and exhibit some clear nonlinearity. Specifically, having a teacher at one of the extremes of the distribution has a big effect on achievement relative to having an average teacher. Referring to the results 36 for model 5 (based on achievement gains), we see that teachers who scored 2 or more standard deviations above the average boosted student gains by 0.068 standard deviations relative to the average teacher, and teachers who scored 2 or more standard deviations below the average reduced achievement gains by 0.062 standard deviations."

What is the WEST-E testing?


How useful are the edTPA field test results?

It's fair to say the edTPA field test results are very early data.  Programs and the test vendor are hard at work making changes to the assessment, so it is impossible exactly how many of these candidates would have passed or failed the final edTPA.  That said, it is likely the edTPA is going to be a big part of a candidate's experience in a Washington educator preparation program and we want candidates to be aware of the information available.

Studies and Reports

It is the intent of all involved to make certain the edTPA correlates with a teacher's success in the classroom, but it is too early for anyone to know for sure.

What is the ProTeach?

The ProTeach is an assessment typically taken between a teachers 3rd and 5th years of teaching.  Results from the ProTeach are connected back to the teacher's WA preparation program.  The ProTeach is not subject-specific, so results are not available by endorsement.  

Studies and Reports

What is "Number Issued" counting?

Many teachers have multiple endorsements.  Also, teachers can add endorsements after they have received their first certificate.  For this application, a teacher with multiple endorsements is counted once for each category within the year they initially received the endorsement.

What is "Currently Teaching in Washington Public Schools" counting?

This information represents whether program completers with particular endorsements are teaching in Washington public schools (paid on Oct 1st for a teacher duty on the S-275).  It is important to note this information does not capture teachers teaching in out-of-state or private schools.  Each of the cohorts in the display is measured against the current working status.  Older cohorts have had more time to begin teaching as well as more time to leave teaching.  

This data is updated when the new year is available from OSPI (typically mid-January).

Why are the numbers different between "Number Issued" and "Currently Teaching in Washington Public Schools"?

This information comes from two sources, OSPI's credential database and annual program data reporting. These systems collect and group this information slightly differently. Also, either or both data may have some error. However they should be reporting similar numbers.
