1. SCORING TERMINOLOGY USED IN ASSESSMENT
Chapter Five

2. After covering this chapter, you should understand the following:
CHAPTER OBJECTIVES
After covering this chapter, you should understand the following:
Calculation of age
Raw scores
Percentiles
Standard scores
z scores
T scores
Stanines
Age equivalents
Grade equivalents

3. The child’s age at the time of testing.
CHRONOLOGICAL AGE
The child’s age at the time of testing.
THINGS TO KEEP IN MIND:
Many children do not know when they were born
Children think they know their date of birth, but are incorrect
Ages are broken down into years, months, and days, something that children would not normally know

4. Normally indicates the number of items correctly answered on
RAW SCORES
Normally indicates the
number of items correctly
answered on
a given test

5. PERCENTILE RANKS (PERCENTILES)
A score indicating the percentage of people or scores that occur at or below a given score.
QUARTILES
DECILES
Divides the scores into four units: 1-25, 26-50, 51-75, and 76—99.
Divides the scores into tenths, or 10 equal units.

6. STANDARD SCORES
A score that has been transformed to fit a normal curve, with a mean and standard deviation that remain the same across ages
Normally have a mean of
100 and a standard
deviation of 15.

7. z Scores
Indicates how many standard deviations a score is above or below the mean
Formula:
z = Test Score – Mean Score/Standard Deviation

8. T Scores Another way to express test performance
Have a mean of 50 with a standard deviation of 10
Formula:
T = z

9. STANINES
An abbreviation for standard nines
A type of standard score that had a mean of 5 and a standard deviation of 2

10. A very general score that is used to compare the
AGE EQUIVALENT SCORES
A very general score that is
used to compare the
performance of children
at the same age with
one another

11. GRADE EQUIVALENT SCORES
A very general score that is used
to compare the performance of
children in the same grade with
one another.
