Term
Definition
 the way individuals adapt themselves to the requirements of their physical and social environment. behaviors that allow an individual to live or keep safe.  Thrive in both good and bad times.
Term
 Mean
Definition
 arithmetic average of scores
Term
 Variance
Definition
 distance between each score and every other score in the test. S2, or O2 measure of the dispersion of scores around the mean of the distribution
Term
 Mode
Definition
 Most frequent score in a distribution.
Term
 Median
Definition
 The middle above 50% of test takers and below 50 % of test takers
Term
 standard deviation
Definition
 S or O positive square root of the variance Bell Curve, 68% average, 28% 1 standard deviation above or below.
Term
 Criterion Referenced
Definition
 for translating test scores into a statement about the behavior to be expected of a person with that score or their relationship to a specified subject matter. Most tests and quizzes written by school teachers are criterion-referenced tests. The objective is simply to see whether the student has learned the material.   Predictive in nature.
Term
 Z-Score
Definition
 basic standard score mean always = 0 standard deviation always= 1 x number of standard deviations above or below the mean. when bell curve looks normal we know the exact z scores.
Term
 T scores
Definition
 average of 50 ranve of 40-60 (68%)
Term
 Reliability
Definition
 Relative absence of random error in measurement item reliability inter observer agreement stability test retest having students take 2 tests to see if they get similar scores.
Term
 When would you use a coefficient alpha ?
Definition
 it is the average of all possible split halves.  you would use it when you want to test reliability through internal consistency. computation of item variance and test variance.
Term
 Validity
Definition
 extent to which interpretation and test scores is supported by evidence and theory. Must be reliable. Specific to individual student. does it lead to correct inferences about the person being tested? Does it measure what it is meant to measure? Correlations.
Term
 Content Validity
Definition
 extent to which a measure represents all facets of a given social construct example, a depression scale may lack content validity if it only assesses the affective dimension of depression but fails to take into account the behavioral dimension
Term
 Criterion Related Validity
Definition
 Concurrent and Predictive is a measure of how well one variable or set of variables predicts an outcome based on information from other variables
Term
 Construct Validity
Definition
 Evaluation of construct validity requires that the correlations of the measure be examined in regards to variables that are known to be related to the construct (purportedly measured by the instrument being evaluated or for which there are theoretical grounds for expecting it to be related
Term
 Formative evaluation
Definition
 formal and informal assessment procedures employed by teachers during the learning process in order to modify teaching and learning activities to improve student attainment
Term
 age equivalent
Definition

similar to that ofthe grade-equivalent score. A raw score corresponds to a chronological age. Ateacher can use a norms table to determine such scores. A portion of a normstable would look something like this:

 --Chronological age-- Raw 6.0 6.6 7.0 7.6 8.0 Score -Age-equivalent score- 20 6.7 6.4 6.2 6.0 5.7 21 6.8 6.5 6.3 6.1 5.8 22 6.9 6.6 6.4 6.2 5.9 23 6.10 6.7 6.5 6.3 5.10
Term
 Correlation Coefficient
Definition
 r, and is typically denoted by r) is a measure of the correlation (linear dependence) between two variables X and Y, giving a value between +1 and −1 inclusive. It is widely used in the sciences as a measure of the strength of linear dependence between two variables
Term
 Assessments: Why are they given?
Definition
 screening: Unrecognized problems? Progress monitoring: are they making progress Instructional planning resource allocation elligibility for special education services (diagnostic) Program evaluation Accountability
Term
 IDEA 2004
Definition
 ederal program that authorizes state and local aid  On December 3, 2004, President Bush signed the Individuals with Disabilities Education Improvement Act, a major reauthorization and revision of IDEA. The new law preserves the basic structure and civil rights guarantees of IDEA but also makes significant changes in the law. Most provisions of Public Law (PL) 108-446 go into effect on July 1, 2005. The requirements regarding “highly qualified” special education teachers became effective immediately upon signature. autism recognized assessement for students with disabilities (alternative assessement) fairness test security confidentiality of information DO NO HARM (best interest)
Term
 MTD (multi disciplinary team) process:
Definition
 collect at minimum what is federally required draw information from variety of sources use well normed reliable sources ETR
Term
 Confidence Interval
Definition
 interval in which a measurement or trial falls corresponding to a given probability. Usually, the confidence interval of interest is symmetrically placed around the mean, so a 50% confidence interval
Term
 SEM (Standard error of measurment)
Definition
 he range within which a person's true score may fall (Drummond, 1996). Its interpretation is based upon theories associated with normal distributions. Basically, we know that 68% of students fall in the average range so it gives us a standard error of measurement to go by.
Term
 types of scoring intervals
Definition
 Nominal scales are data that record categories. Ordinal scales record information about the rank order of scores. Interval scales tell us about the order of data points, and the size of the intervals in between data points. A ratio scale is an interval scale with a true zero point.
Term
 out of level testing
Definition
 The literature indicates that the benefit of out-of-level testing is that it is a cost-effective method for increasing the precision with which low performing students’ ability is measured. However, an unreported downside is that the process by which scores on out-of-level testing are converted back into the scale of the in-level test reduces measurement precision. Further, it has not been demonstrated that more precision is gained than is lost. most students with special needs are tested out of level on OAA's and the graduation test
Term
 scores and norms
Definition
 To understand norms and statistical assessment one first needs to understand standardization. Standardization is the process of testing a group of people to see the scores that are typically attained. With a standardized test, the participant can compare where that score fell compared to the standardization group's performance. With standardization the normative group must reflect the population for which the test was designed. The group's performance is the basis for the tests norms.
Term
 Entitlement
Definition
