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.
