  6. 6. ©2003-2013 Carolyn Kottmeyer Ability Test Terms… Criterion-referenced (CRT)  Measure how well a person has learned a specific body of knowledge and skills  Content based on its significance in the curriculum Norm-referenced (NRT)  Compare an individual's score against the scores of a group who took the same exam, the “norm group” or “standardization sample”  Content is chosen by how well it discriminates among students Some tests allow both comparisons…
  7. 7. ©2003-2013 Carolyn Kottmeyer Scoring terms… Mean  Average score on test  IQ test expected to have mean of 100 Standard deviation (SD)  Statistical term: difference from norm  Two standard deviations above average is considered gifted  130+ (for standard deviation of 15)
  8. 8. ©2003-2013 Carolyn Kottmeyer Normal Distribution Distribution of IQ Scores http://encarta.msn.com/media_461540296/Distribution_of_IQ_Scores.html
  9. 9. ©2003-2013 Carolyn Kottmeyer Scoring terms… Standard score  Looks like IQ score, but may be very limited  Mean = 100  standard deviation may or may not = 15 Age Equivalent Grade Equivalent  Age / grade of average students with this score (http://alpha.fdu.edu/psychology/oat_cereal.htm)
  10. 10. ©2003-2013 Carolyn Kottmeyer Scoring terms… Percent Correct  90% means 90/100 (or 45/50 or 9/10) correct Percentile  If 10% of norming group got 100% correct, perfect score is 90th percentile  50th percentile means average Raw score  Items correct of items attempted
  11. 11. ©2003-2013 Carolyn Kottmeyer Grade Level Achievement Test Standardized for one grade level only  Or less… early elementary grades have different norms / tests available for fall and spring testing Grade equivalents compare how child of grade x would do on this grade level’s test  NOT how this child would do on grade level x test! Group test  Testing in the classroom has built-in distractions…
  12. 12. ©2003-2013 Carolyn Kottmeyer Grade Level Achievement Test Nationally normed  ITBS, CAT-5, SAT 9, Terra Nova, CTBS, MAT  Norm referenced (ITBS scores as both norm and criterion referenced) State mandated tests  ESPA, GEPA, PSSA (Pennsylvania), TAAS, TAKS (Texas)  Criterion referenced  MCAS (Massachusetts)  Norm referenced, sort of…
  13. 13. ©2003-2013 Carolyn Kottmeyer Out-of-Level Achievement Test Comprehensive achievement tests  Developed for Talent Search or private schools  More comprehensive content than typical group achievement tests Given to students 2-5 years younger than norms “Combs out” upper level achievement  95th-99th percentiles are spread across entire percentile spectrum on higher level test
  14. 14. ©2003-2013 Carolyn Kottmeyer Out-of-Level Testing Used by Talent Search programs  Johns Hopkins CTY / Northwestern CTD / Duke TIP / Rocky Mountain Talent Search  Carnegie Mellon C-MITES Identify gifted students vs. high achievers  Those still scoring in higher percentiles on 2-4 grade level higher test  Usually 50th percentile or above Examples: SCAT, Plus, Explore, SAT
  15. 15. ©2003-2013 Carolyn Kottmeyer Individual Achievement Test Less questions per grade level, but more grade levels covered Norm-referenced scoring  Compares child to average child of age/grade level  Does NOT evaluate child on specific curriculum content Examples  WIAT (Wechsler)  K-TEA (Kaufman)  PIAT (Peabody)  WJ-III (Woodcock Johnson)
  16. 16. ©2003-2013 Carolyn Kottmeyer Individual Achievement Test Watch for test ceilings  Average 12th grade math = Algebra I  Average 12th grade reading level… Use WJ-III for older gifted kids  12th grade ceilings on WIAT / PIAT / K-TEA  18th grade ceiling on WJ-III  18th grade is NOT post-graduate
  17. 17. ©2003-2013 Carolyn Kottmeyer Individual Achievement Test Scores Scores include  Percentile  Standard score  Age and grade equivalent If school doesn’t share all scores, insist!  FERPA Can also report score as if in higher grade  Child is rising 3rd grader, report scores also as a rising 4th grader to see how child would compare to potential classmates
  18. 18. ©2003-2013 Carolyn Kottmeyer Curriculum Based Assessment (CBA) Most valid for comparing child’s achievement to school’s curriculum Uses actual curriculum materials  Standard midterm or final exam  Compiled from end of chapter tests  NOT chapter test after chapter test after chapter test after…
  19. 19. ©2003-2013 Carolyn Kottmeyer Curriculum Based Assessment (CBA) Conducted thoughtfully…  Review may be allowed  Answer terminology questions during testing Scored reasonably…  85% - 90% correct  Perfection is NOT the goal  If the child doesn’t get required 85-90%, parts of subject already mastered need to be skipped
  20. 20. ©2003-2013 Carolyn Kottmeyer Test Scores vs. Classroom Placement 1. Curriculum Based Assessment  CBA level = grade level 2. Out of level Achievement Test  Comprehensive and above level 3. Individual Achievement Test  Not as comprehensive for each grade level  Compared to average students (norm-referenced)  Useful for comparing child to heterogeneous elementary school classroom 4. Group Achievement Test  Tested grade level only  Shows child is at or below grade level
  21. 21. ©2003-2013 Carolyn Kottmeyer Ability / IQ Test Ability vs. Intelligence?  Terms are interchangeable Some tests are more widely accepted, and have a more stable test/retest and test to test correlation  Buros Mental Measurements Yearbook  Library reference section or  www.unl.edu/buros/
  22. 22. ©2003-2013 Carolyn Kottmeyer Group Screening Measures Be aware…  Normalization sample size  Mean, deviation, and standard measure of error  Hard ceiling score GATES and others  Survey – only as good as teacher-training SAGES and others  Group test of both ability and achievement
  23. 23. ©2003-2013 Carolyn Kottmeyer Group Ability Test Same problems as group achievement tests  Written for a single grade level  Administered in classroom environment Group ability tests often underestimate scores later received on individual tests Examples:  OLSAT (Otis Lennon Scholastic Abilities Test)  CogAT (Cognitive Abilities Test) Co-normed with ITBS
  24. 24. ©2003-2013 Carolyn Kottmeyer Group Ability Test Gifted children often over-think the questions  No chance for tester to say, “What did you mean by that?” “What’s a more common answer?” Study shows Reverse correlation between group ability test scores and gifted children  The more gifted, the LOWER the test score! Study shows LD/2e children underestimated  These children are more accurately identified by individual IQ test
  25. 25. ©2003-2013 Carolyn Kottmeyer Individual Ability Test Considered best estimate of ability  Still not perfect!  Test style vs. child’s strengths  Tester vs. child “fit” Examples:  Wechsler series (WPPSI-III, WISC- IV, WAIS-IV)  Stanford-Binet (SB-5)  Differential Ability Scales (DAS-II)
  26. 26. ©2003-2013 Carolyn Kottmeyer Intelligence (IQ) Test Less commonly used individual tests  WJ-III cognitive (Woodcock Johnson)  Different definition of intelligence  Excellent for locating LDs in 2e child  K-ABC (Kaufman Assessment Battery for Children)  Lots more… Inventory of Tests www.hoagiesgifted.org/tests.htm
  27. 27. ©2003-2013 Carolyn Kottmeyer Intelligence (IQ) Test Nonverbal tests  Naglieri Nonverbal Ability Test (NNAT)  UNIT (Universal Nonverbal…)  Ravens (group)  Research shows NO cultural “fairness” in non- verbal tests  David Lohman, University of Iowa
  28. 28. ©2003-2013 Carolyn Kottmeyer IQ Test Ceilings WISC-IV, WPPSI-III and SB-5  Ceiling of Full Scale 160 (SD=15) WJ-III Cognitive  Ceiling of GIA depends on student age (SD=15) DAS (Differential Abilities Scales)  Ceiling of General 175 (SD=15) Other tests usually ceiling=160, SD=15
  29. 29. ©2003-2013 Carolyn Kottmeyer IQ Subtest Ceilings WISC-IV / SB-5  Subtests at scaled scores 17-19 (99th percentile)  Penalties for careful and thoughtful completion (speed bonus)  By some age, a child can get every WISC-III question right, and still score under 130 due to time penalties!  Better on WISC-IV, but still strong time bias
  30. 30. ©2003-2013 Carolyn Kottmeyer IQ Testing WISC (Wechsler) "He [Dr. Wechsler] rejected most attempts that I made to add easy or hard items to the WISC-R saying firmly, 'My scales are meant for people with average or near-average intelligence, clinical patients who score between 70 and 130.'" "They are clinical tests." When I reminded him that psychologists commonly use his scales for the extremes, and want to make distinctions with the 'below 70' and 'above 130' groups, he answered, "Then that is their misfortune. It's not what I tell them to do, and it's not what a good clinician ought to do. They should know better." (Kaufman, Intelligent testing with the WISC-III ,1994)
  31. 31. ©2003-2013 Carolyn Kottmeyer IQ Subtest Ceilings WISC-IV and WPPSI-III  The WISC is not a good measure for children scoring outside of 3 deviations from the mean. An average subtest score of 14 or 15 is 2 standard deviations outside the mean, an average subtest score of 16 or 17 is 3 standard deviations outside the mean. Sattler and Dumont do not discuss the use of the test above those levels at all…  Summary of Assessment of Children WISC-IV and WPPSI-III Supplement, by Sattler and Dumont
  32. 32. ©2003-2013 Carolyn Kottmeyer The View from the Ceiling… Was completion criteria reached?  Completion criteria:  <3 questions correct of 5 consecutive asked Did student run out of test questions, or score possibilities?  If student answered more questions correctly, could score increase?
  33. 33. ©2003-2013 Carolyn Kottmeyer Flynn Effect According to Flynn… IQ increases by 3 points every 10 years Does Flynn effect apply at the extremes?  From SB-4 to SB-5, ~4 points at mean=100  Gifted sample SB-4 to SB-5 scores vary by 7+
  34. 34. ©2003-2013 Carolyn Kottmeyer Flynn Flam…? Smart as We Can Get?: Gains on certain tests of intelligence are ending in some places, American Scientist http://www.americanscientist.org/ Some countries are experiencing a Flynn effect with a reversed sign…
