    or Obtained a full credit on the start-point item but not on

    Reverse sequencing

    When using the reverse sequence, if the

    discontinue criterion is not met and the

    individual either has two consecutive items

    with the perfect scores or has reached item 1,continue administration with the next

    appropriate item after the start-point item (3).

    Scoring guidelines

    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.

    18/29

    Scoring guidelines

    For items 5, 8, 9 and 10 (items that require two general concepts)give 2 points only to responses that clearly refers to two differentgeneral concepts. Give 1 point to responses that refers to samegeneral concept.

    Added or personalized remarks that do not spoil the response do

    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.

    Do not award points for any items administered beyond the last

    score of 0 required for the discontinue criterion to be met.
