We can all agree that the interpretation of cognitive test scores mostly leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Knowing this fact, it is absolutely necessary for us, as future school psychologists, to administer and score cognitive tests without any errors.
A recent study published in Psychology in the Schools (Graduate students’ administration and scoring errors on the Woodcock-Johnston III Tests of Cognitive Abilities, vol.46, issue 7, pgs. 650-657, July 2009) looked at the frequency and the types of errors that occurred during administration and scoring of Woodcock Johnston III Tests of Cognitive Abilities (WJ III COG). Data from 36 graduate students across 108 test records revealed a total of 500 errors across all records!!!! Three frequently occurring errors included the use of incorrect ceilings, failure to record errors, and failure to encircle the correct row for the total number correct.
Can we avoid making scoring errors on cognitive tests and if so how? Are these errors more likely to occur on WJ III or they happen regardless of the test used? Are we properly trained to administer cognitive tests? Do you think that wrong scores may result in some children being placed in the wrong settings?
And finally…What can our graduate programs do to ensure that we are all properly trained to administer cognitive tests?
