Produces a raw score that converts to a scale score of 0-200.

Allows for students to be classified into one of three categories: Below the Standards, Meets the Standards, Exceeds the Standards.

Provides comparability across Nebraska school buildings and districts.

~NeSA Terminology~

What is the difference between a raw score and a scale score?

What is a raw score?A raw score is the number of correct items. Raw scores have been typically used in classrooms as percentages: 18/20= 90% correct.

24

~NeSA Terminology~

What is a scale score?

A scale score is a “transformation” of the number of items answered correctly to a score that can be more easily interpreted between tests and over time. The scale score maintains the rank order of students (i.e., a student who answers more items correctly gets a higher scale score). For NeSA, we selected 0-200 and will use it for all NeSA tests, including writing.

25

~NeSA Terminology~

Why convert raw scores to scale scores?

Raw scores are converted to scale scores in order to compare scores from year to year. Raw scores should not be compared over time because items vary in difficulty level. Additionally, raw scores should not be compared across different content area tests. Scale scores add stability to data collected over time that raw scores do not provide.

26

~NeSA Terminology~

SCALE SCORE CONVERTED TO PERCENTILE RANK?

On score reports why is the . . .

The percentile rank was placed on the score reports because our Technical Advisory Committee felt that parents would want to know their child’s position in relation to other test takers.

A percentile rank of 84 means the child scored better than 84% of the students who took the test that year.

NeSA (CRT) vs. NRT ?

28

--Differences--

Purposes: NeSA is intended to match and measure identified standards and instruction.NRT is not intended to measure any state’s standards. The intention is to compare students to each other.Item Development:NeSA items with exact match to the standards – NDE had to prove the match with an independent alignment studyNRT – No standards to match – matches inherent and previous knowledge, enriched homes, pre-skills.

--Similarities—All the psychometric steps – standard setting (Bookmark, Angoff, Contrasting Group)Reliabilities – KR 20-21 / Inter-rater ReliabilitiesDescriptive Statistics (Item P-values, Dif-analysis)

Administration:Both standardized – are generally administered the same way.

NeSA results ARE an important data source!

When combined with other information, these data can support curricular, instructional, and learning support

decision making.

Improvement Process!
