INTELLIGENCE TESTING OF INDIVIDUALS WHO ARE BLIND OR VISUALLY IMPAIRED: • A Position Paper
THE BEGINNING… • APH established a task force in January, 2007 • Asked question of task force: • “Do IQ tests provide meaningful information for individuals with visual impairment?”
THE ANSWER… • The Task Force responded that : • “IQ tests can provide meaningful information for • the individual, as well as their instructors, families, and decision-makers.”
HOWEVER, IT IS IMPORTANT: • “…that all tests be administered in accordance with key points that reflect the uniqueness of the population, as well as appropriate cautions.”
THE TASK FORCE STARTS: • The Task Force developed a position paper and key points that reflect: • Appropriate preparation for administration • Cautions in administration • Cautions in interpretation
CONTENTS OF POSITION PAPER CONSIST OF: • PREPARATION • Administration • Specialized Training Needed • Reasons for Evaluation • Collaboration between Disciplines • Eye Conditions and Developmental History
(Continued) • ADMINISTRATION • Adaptations • Tactile and Symbolic Representation
(Continued) • INTERPRETATION • Qualitative interpretation • Reporting Results
POSITION STATEMENT • When appropriate practices • are followed, cognitive or • intelligence testing of • individuals who are blind or VI • provides useful and valuable • information to test-takers, their • families, instructors, and other • decision makers.
ISSUE 1: ADMINISTERING INTELLIGENCE TESTS • GUIDELINE 1: • Intelligence test results yield • valuable information about • an individual and increase the • usefulness of the overall • evaluation.
PRIOR TO ADMINISTRATION THE EVALUATOR MUST: • Ensure completion of • Functional Vision/Learning • Media Assessment (FV/LMA) • by a TVI or O&M Specialist
( Continued) • Understand information contained in the FV/LMA and ways to use it in testing: • FV discusses ways to present materials for individual’s use of vision • LMA discusses best media for different tasks
(Continued) • Understand the impact of adaptations and modifications upon test results • Understand the importance of making tests accessible without change of content • Support of collaborative evaluations for ensuring the highest quality
SUGGESTED RESOURCE • Functional Vision • and Learning Media • Assessment (FVLMA) • FVLMA Kit: 7-96151-00 $67.00 • (Grades K-12; pre-academic or academic) • American Printing House for the Blind
ISSUE 2: SPECIALIZED TRAINING • Guideline 2: • Those administering tests need • specialized training in theory of • assessment and test • construction as well as child • development and • communication methods of • individuals who are blind or VI.
Professional Preparation of Evaluator must include: • Constructs of intelligence • Theory of tests and measurement • Typical and atypical child development • Test administration with general and special populations • Understanding of collaborative evaluations
The Professional Evaluator must: • Accept the concept of collaborative evaluation • Incorporate expertise of VI professionals in the evaluation process • Collaborate in all phases from preparation for testing to report writing
SUGGESTED RESOURCE • Collaborative Assessment: Working with Students who are Blind or Visually Impaired Including Those with Additional Disabilities • American Foundation for the Blind
ISSUE 3: REASONS FOR EVALUATION • Guideline 3: • The reason for the evaluation, • and the resulting specific • clinical judgments and • recommendations, should be • clearly documented in each • individual’s report.
The Evaluator must: • Request information about specific reasons for evaluation • Avoid accepting reasons that relate only to regulations
Specificity of these requests will: • Improve test selection • Answer referral questions • Minimize simple reporting of scores • Increase applicability of results
The Recommendations should: • Be clear to all stakeholders • Avoid professional jargon • Explain technical terms • Make recommendations that apply to real-life situations • Focus on increasing independence and self-advocacy
The Evaluation should not be used as the sole determinant of: • Cognitive abilities • Presence of additional disabilities • Eligibility for special programs
SUGGESTED RESOURCE • Making Evaluation Meaningful: Determining Additional Eligibilities and Appropriate Instructional Strategies • Texas School for the Blind and Visually Impaired
ISSUE 4: COLLABORATION • Guideline 4: • The visual impairment and/or • rehabilitation professional, • classroom teacher, family, and • individual must be involved during • the planning, evaluation, and • report writing process.
COLLABORATIVE EVALUATIONS WILL ALWAYS: • Gather information from all individuals • Actively solicit and discuss information • View collaboration as an on-going process • Reflect the professional expertise of all
ISSUE 5: EYE CONDITION AND DEVELOPMENTAL HISTORY • Guideline 5: • The evaluator should be aware of • the individual’s medical and • developmental history, as well as • the implications of the eye condition • on the tasks to be performed (and • implementation of recommendations)
Specific necessary information includes understanding of: • Medical history • Developmental patterns and relationship to vision • Early intervention • Congenital vs. Adventitious vision loss • Neurological vs. Ocular vision problems
ISSUE 6: ADAPTATIONS • Guideline 6: • Adaptations, which include • accommodations that do not change • the concepts tested nor the difficulty • level of the test materials, should be • planned in advance in collaboration • with the visual impairment and/or • rehabilitation professional and the • test developer, and be well- • documented in the final report.
SUGGESTED RESOURCE • Developmental Guidelines for Infants with Visual Impairments: A Guidebook for Early Intervention, 2nd Edition • Print with CD-ROM: 8-50701-00 $95.00 • American Printing House for the Blind
ACCOMMODATIONS SHOULD BE: • Made only to provide access to the test taker • Planned in advance • Made in such a manner that DOES NOT affect the basic concept or difficulty of item • Documented in final report
ACCOMMODATION OR MODIFICATION? • Accommodations do not affect basic concept or difficulty, e.g. braille or LP • Modifications affect basic concept or difficulty, e.g. use of calculator • Either change increases the need for caution in interpretation of results
ISSUE 7: TACTILE AND SYMBOLIC REPRESENTATIONS • Guideline 7: • Symbols, tactile graphics, and • miniature objects must be • carefully considered and used • with caution to represent pictorial • or graphical information. Real • objects should be used whenever • feasible.
Visual stimuli must be carefully analyzed to determine • Relevance to the concept being assessed • Stimuli that can be made accessible • Any changes or eliminations • Appropriate use of miniature objects unless familiarity is ensured
ISSUE 8: DIRECT OBSERVATION • Guideline 8: • The assessment should include • direct observation in multiple • situations.
Suggested behaviors for observation include: • Visual efficiency • Visual fatigue • Organizational abilities required in problem-solving • Application of O&M skills in new environments • Presence of self-stimulatory behaviors
Additional information should include: • Social integration with peers • Independent initiation of activities • Organization of tasks for successful management and completion • Self-advocacy skills • Self-management of technology
ISSUE 9: QUALITATIVE INTERPRETATION • Guideline 9: • When visual-spatial items or tests • are administered, these results • should be used only for clinical • purposes and to identify • appropriate modifications of • educational or vocational materials • and instructional methods. • (continued )
Guideline 9 (continued) • Results obtained from visual- • spatial evaluations must never be • reported as scores or used to • determine the presence of other • disabilities. Important exceptions • to this guideline exist, and are • documented below.
Visual-Spatial items or tests may be administered if: • The individual uses vision for learning • The FV and LMA support the presence of adequate vision for specific items • Both the VI professional and Evaluator agree that results provide meaningful information AND support the referral question
Accommodations made to Visual-Spatial items/test must be: • Supported by the FV/LMA • Endorsed by both vision professional and evaluator • Noted in the final report • Include such things as extending time and use of CCTV during administration
Results of performance on Visual-Spatial items or tests should be: • Reported qualitatively rather than a score • Used as a source to determine learning strengths • Used to plan meaningful accommodations in different environments
ISSUE 10: REPORTING RESULTS • Guideline 10: • Reports of assessments of • individuals with visual impairments • need to be expanded to include an • explanation of the procedures • followed, changes in standardized • administration, and the description • of performance observed.
GENERAL CAUTIONS • All reports should reflect that tests represent an estimate of abilities • Standardization of most-frequently administered tests did not include persons with visual impairments
Test results should be reported with the Evaluator specifying: • Intervals around the obtained score as well as specific score • Confidence intervals at 90% level • Specific concerns relating to validity of scores • (continued )
(Continued) • Any adaptations in procedures and/or materials • Lack of norms for individual who is blind or visually impaired and corresponding cautions • Accommodations to provide access are specified
REPORTING RESULTS OF VISUAL SPATIAL TESTS • Extreme caution must be used in reporting scores on visual spatial tests • Generally these must be reported qualitatively: i.e. as strengths and weaknesses
