refers to the consistency of scores across replications of a testing procedure
What is reliability
100
the degree to which evidence and theory support the interpretations of test scores for proposed uses of tests
What is validity?
100
Whether the order or ranking of scores across raters or observers is similar
What is interrator score reliability
100
the perceived usefulness of the items on a test
Acceptability, feasibility, and satisfaction with the outcome
What is social validity?
100
tells the average age at which 50% of the normative sample achieved a particular raw score
What is age-equivalent scores/developmental age scores?
200
characteristics of the instrument, characteristics of the children and of the administration, characteristics of the examiner
What is sources of error
200
Whether the items on a test represent the construct being measured
What is content validity evidence?
200
the consistency of test scores when administered to the same group of individuals within a short period of time
What is test-retest reliability
200
the degree to which test results contribute to intervention or teaching
What is instructional or intervention utility?
200
tells what percentage of the population performed at or below a given score
What is percentile rank?
300
the extent to which the administration procedures for a particular assessment instrument are followed
What is procedural accuracy
300
the degree to which relationships among responses to assessment items conform to expectations about the construct
What is internal structure validity evidence?
300
the consistency between scores on alternate forms of a test
What is alternate forms reliability
300
determining presence of factors in the instrument
What is factor analysis?
300
a score that has been transformed to fit the normal curve and has a mean of 100 and a standard deviation of 15
What is developmental quotient?
400
the extent to which the score calculations and score summaries are correct
What is scoring accuracy
400
correlation between test scores and the scores of another currently used instrument
What is concurrent validity?
400
consistency of a child’s performance across items within a test
What is internal consistency
400
scores from assessment instruments that purportedly measure a particular construct should correlated strongly with scores from other instruments that measure the same construct
What is convergent score validity?
400
Gives an estimated range of scores which is likely to include the true score. It provides the probability that a true score will fall within a particular range of scores.
What is confident interval?
500
The extent to which individuals concur on their scores
What is interrator or interobserver agreement
500
correlation between test scores and future performance on an
assessment that measures the same construct
What is predictive validity?
500
a hypothetical construct that indicates how consistent a performance would be if a child took the test many times
What is standard error of measurement
500
correlate weakly or inversely with scores from an assessment instrument that measure a different construct
What is discriminant score validity?
500
a number that helps in interpreting where any particular score falls along the distribution of scores by describing how far the score is from the mean
