    Study Notes

    What is Standardized about Standardized Testing?

    • Standardization refers to the administration, scoring, and interpretation of the test being the same everywhere and every time.
    • It ensures each student takes the test under the same conditions, with the same amount of time, instructions, and assistance.
    • Standardization does not refer to the specific items on the test.

    Types of Standardized Tests

    • There are two types of standardized tests: Achievement and Aptitude.
    • Achievement Tests measure a student's mastery of what they have learned in the past and what they can perform in the present.
    • Examples of Achievement Tests include Ohio Achievement Tests (OATs), Ohio Graduation Test (OGT), and Iowa Test of Basic Skills (ITBS).
    • Aptitude Tests measure how much promise a student has for the future and predict their future performance statistically.
    • Examples of Aptitude Tests include Scholastic Aptitude Test (SAT), ACT, and PSAT.

    Reporting Standardized Test Scores

    • Test scores can be reported as Criterion-Referenced or Norm Referenced.
    • Criterion-Referenced scores are relatively easy to understand and include Number and Percent Correct, Performance Speed, Performance Quality, and Performance Precision.
    • Norm Referenced scores compare students with each other and include Raw Scores, Percentile Ranks, Grade Level Equivalents, and Standardized Scores.

    Norm Referenced Scores

    • Raw Scores are not very useful for comparing students.
    • Percentile Ranks show the percentage of students who scored below a particular student.
    • Grade Level Equivalents report a student's score in terms of the grade level they are expected to be in.
    • Standardized Scores, such as z-scores and t-scores, are transformations of raw scores and can be compared from test to test and student to student.

    z-scores and t-scores

    • z-scores are calculated based on the mean and standard deviation of the normal distribution.
    • z-scores are standardized and can be compared from test to test and student to student.
    • t-scores are larger than z-scores and use z-scores as the baseline for transformation.

    Other Standardized Scores

    • SAT and GRE tests have a Mean of 500 and SD of 100.
    • IQ tests have a Mean of 100 and SD of 15 (or 16).
    • Stanines (standard nine) were created on a 9-pt scale with a Mean of 5 and SD of 2.
    • Normal Curve Equivalents (NCE) are similar to Percentile Ranks, but NCEs are equal interval and Percentile Ranks are not.

    What makes up a test score?

    • No test measures ability perfectly; instead, test scores are made up of two components: Ability and Standard Error (or noise).
    • Test Score = Ability + Standard Error (SEM)
    • SEM = The average amount of measurement error across students in the norm group.
