The test-retest reliability of the kindergarten diagnostic instrument
The purpose of this study was to determine the test-retest reliability of the Kindergarten Diagnostic Instrument (KDI). The KDI was administered to 59 preschool children between the ages of four and one-half to six years. After a period of three weeks, the same children were retested with the KDI. A Pearson Product Moment Correlation was calculated between the first and second KDI Total Test Scores and yielded a correlation coefficient of .91. Pearson Product Moment Correlations were also calculated between the first and second administrations of the KDI for each of the 13 subtests. These individual subtest reliability coefficients ranged from .16 to .81. Implications for the diagnostic and prescriptive uses of the KDI were discussed.
