Cognitive Linguistic Quick Test-Plus


Overview: Quickly measure cognitive and linguistic strengths and weaknesses

Age Range: 18 to 89 years

Completion Time: 15 to 30 minutes

Publication Date: 2001 (CLQT); 2017 (CLQT+)


Product Details

Leading neurobehavioral researcher and author, Nancy Helm-Estabrooks, ScD, designed the criterion-referenced Cognitive Linguistic Quick Test (CLQT) to assist you in quickly assessing strengths and weaknesses in five cognitive domains (Attention, Memory, Executive Functions, Language, and Visuospatial Skills). Now, the CLQT+ adds an important element--an optional new administration path for people with aphasia. Including one new semantic comprehension task and scoring for several elements within the current tasks, the CLQT+ gives you:

  • more flexibility in your administration
  • clearer interpretation for people with aphasia
  • the same foundation for a quick, reliable cognitive assessment at table or bedside
  • an effective tool for English- or Spanish-speaking adults with known or suspected neurological impairment as a result of stroke, traumatic brain injury, or dementia.

Content and Administration

CLQT+ offers two standard administration paths--a Traditional Administration and an Aphasia Administration. Whether you administer at bedside or in an office, the tasks administered for each path are slightly different:

Traditional Administration

Aphasia Administration

  • Personal Facts
  • Symbol Cancellation
  • Confrontation Naming
  • Clock Drawing
  • Story Retelling
  • Symbol Trails
  • Generative Naming
  • Design Memory
  • Mazes
  • Design Generation

  • Design Generation
  • Semantic Comprehension


*Additional points scored for following auditory directions within this task for the Aphasia Administration.

Users and Applications

The CLQT+ can be used by:

  • Speech-language pathologists
  • Occupational therapists
  • Psychologists/Neuropsychologists
  • Other qualified professionals interested in a quick measure of cognitive/linguistic status

Use the CLQT+ test:

  • as part of a larger screening/assessment process
  • for intervention planning and progress monitoring

The CLQT+ is particularly suited for several special uses:

  • Progress monitoring--Because of its brief administration time, the CLQT+ may be used at intervals in recovery to show progress. In particular, the Clock Drawing task may be used descriptively as a "mini-screen" of cognitive status--every few days to a week in recovery or at an interval of at least two months with cognitive decline, such as dementia.

  • Driving assessments--Occupational therapists and related professionals may use the CLQT+ as part of a larger assessment process on driving readiness, to quickly assess cognitive skills needed for safe and successful vehicle operation.

  • Competency assessment--Now with the Aphasia Administration, individuals with language impairment/aphasia can show cognitive ability levels apart from a language disorder.

  • Research--In adults with multiple types of neurological impact (e.g., TBI, stroke, neurodegenerative disease), professionals may use the CLQT+ due to its comprehensive focus in connection with its efficient administration time for patients of all severity levels.

Psychometric Information

Original CLQT

One pilot (n=13) and three studies (n=92, 154, and 119, respectively) established the reliability and validity of the CLQT. Criterion cut scores, domain scores, and severity ratings were developed from these data sets along with the author's clinical expertise.

Aphasia sample (CLQT+)

One clinical study including 76 individuals diagnosed with aphasia associated with left hemisphere strokes were given the revised version of the CLQT. Consistent with the original CLQT data, scores have been provided for two age groups: ages 18–69 and ages 70–89. In general, as expected, average task scores are lower for the aphasia sample compared to the nonclinical sample.

  • Why are some items listed as “CLQT” and some as “CLQT+?”

    Those items that are listed as “CLQT” are components that did not change between the original CLQT release and the release of the CLQT+.

  • I already have the CLQT kit. What do I need to purchase to use the CLQT+?

    You can purchase the following individual components:

    • Record Forms (25):
      • 0158010604 CLQT+, or
      • 0158008189 CLQT+ Response Booklets English/Spanish & English
    • 0158008197 CLQT+ Stimulus Manual
    • 0158009746 CLQT+ Manual Supplement


  • On Symbol Trails, the examinee did Trials 1 & 2 correctly, but did not follow the instructions on the actual scored task. The examinee kept repeating “circle to triangle,” but she drew the lines in a scattered fashion, not paying attention to connecting circles to triangles or connecting objects of increasing size. According to the scoring criteria, the examinee completed 7 lines correct. Is the score actually 7? Should she consider the subtest to be spoiled?

    If the examiner follows the guidelines for instructions to the examinee, credit should be given for the lines connected correctly. The score is indeed a 7 and scoring procedures should be followed and reported. At the same time, the clinician needs to make a judgment whether or not that score appears to be reflective of intentional performance or not and qualify those concerns in the report. Certainly, the verbal repetition “circle to triangle” could be an indicator of lack of attention and “random drawing” (which ended up being rather accurate in this case), or it could simply be verbal rehearsal and a perseverating self-monitoring strategy during the task. Only the clinician giving the test can make the best judgment about that. The scoring, however, is based on actual performance given correct administration procedures.

  • On Design Memory, how would you handle a response after 10 seconds? Would it just be marked as incorrect since it states under the time limit "allow 10 seconds", or would you prompt and then score their response? The Manual states under the repeating directions and stimuli section "if the examinee does not attempt to respond withing 10 seconds". However, it also states "Do not give credit for any responses completed after the time limit." 

    If the examinee does not respond to the item after 10 seconds, score the item as incorrect. According to the manual, you may repeat the directions once at the 10 second mark. You may record descriptively if the examinee responds (correctly or incorrectly) after the 10 seconds, but you may not re-score the item after the 10 second mark.
