The comprehension subset is difficult to score becauseindividuals may give responses that differ from thoseprovided in the Manual.
Score all the items as 0, 1, or 2. an incorrect responsereceives a score of 0, a less adequate but correct generalresponse receives a score of 1 and a fully adequate generalconcept response receives a score of 2.
Score the response given to your query rather than theinitial response.
When part of a response vary in quality but none spoil theentire response, score the best part of the response.
Give 0 point for the multiple responses.

not affect the score. When the individual earns perfect scores on the first two items at
the start point or in a reversal award full credit to all the proceedingitems, regardless of the individuals performance on these items ifthey have been administered.
