A score, derived from student responses to the NAEP assessment items that summarizes the overall level of performance attained by that student. NAEP subject area scores are typically expressed on 0-500 (reading, mathematics, history, and geography) or 0-300 (science, writing, and civics) scales. When used in conjunction with interpretive aids, such as item maps, they provide information about what a particular aggregate of students in the population knows and can do.
Underlying score from which all other scores are calculated; on the CTBS the scale score is a range of 100-999 representing a continuum from kindergarten through grade 12; as a child gets older, the scale score should be going up to represent growth in learning.
a conversion of the number of correctly answered questions (the raw score )
a score on a numeric scale with intervals of equal size
a transformed raw test score (the number of test questions answered correctly given the length of the test taken)
A scale score places performance on each state exam on the same scale, and is used to determine whether each student passed, and if so, at what level.
Many tests use this as the basic measure of the student's performance. It is used primarily to provide a basis for deriving various other normative scores to describe performance (like percentile ranks). The scale score is also the basis for setting the proficiency performance levels for the WSAS and Third Grade Reading Tests (i.e., advanced, proficient, basic, minimal). The Terra Nova test series, which is the test used for WSAS, extends from Kindergarten through 12th grade versions and has a scale score range across those levels of 0 to 999. Other tests have different scale ranges such as college admissions tests like the ACT (range of 0 to 36) and the SAT (range of 0 to 1600). Scale scores are calculated by applying sophisticated computational procedures directly to the pattern of student responses to the items or questions.
Derived from overall level of performance of groups of students on NAEP assessment items. NAEP subject area scale scores are typically expressed on 0–500 (reading, mathematics, history, and geography) or 0–300 (science, writing, and civics) scales. When used in conjunction with interpretive aids, such as item maps, they provide information about what a particular aggregate of students in the population knows and can do. NOTE: In other testing programs, the scale score is derived from individual student responses to assessment items and summarizes the overall level of performance attained by that student. In NAEP, no individual scale scores are available.
This refers to a type of converted score that may be used by an exam program. Scale scores may be established for an exam program so that all of the test forms can be converted and then reported on the same scale. Over time, the scale score values of the scale score acquire meaning as stakeholders become familiar with the level of performance reflected in specific numeric values. A scale score, like a percentile rank score, has a norm-referenced type of interpretation.
A score that expresses the results of a particular assessment on a single common scale. Scale scores are a type of standard score (see below). They permit comparisons from grade to grade, across time, or among different forms of an assessment.
A scale score may be reported on both NRTs and CRTs. Scale scores are mathematical conversions from raw scores to a new, arbitrarily chosen scale to represent student achievement. They have no inherent or readily apparent meaning. The better a student performs on a test, the higher the scale score reported. Each test publisher can determine its own scale range to represent achievement. Practitioners must know the scale range of the test in order to interpret a student's achievement. In the state of Florida, standards were set resulting in FCAT achievement levels as a way of integrating the results of the grade level scale scores.
Uses a set scale (e.g., 0–500 on the National Assessment of Educational Progress [NAEP] reading and mathematics assessments) to assess overall achievement in a domain, such as mathematics. NAEP and the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS–K) use Item Response Theory (IRT) models to determine the scale. (See Score.)
