Types
There are several general classes of reliability estimates:
- Inter-rater reliability assesses the degree to which test scores are consistent when measurements are taken by different people using the same methods.
- Test-retest reliability assesses the degree to which test scores are consistent from one test administration to the next. Measurements are gathered from a single rater who uses the same methods or instruments and the same testing conditions. This includes intra-rater reliability.
- Inter-method reliability assesses the degree to which test scores are consistent when there is a variation in the methods or instruments used. This allows inter-rater reliability to be ruled out. When dealing with forms, it may be termed parallel-forms reliability.
- Internal consistency reliability, assesses the consistency of results across items within a test.

“He types his laboured column—weary drudge!
Senile fudge and solemn:

These dry leaves of his autumn.”
