Transcript

  • 1. Understanding YourChild’s ITBS Test Scores Kary S. Kublin, Ph.D., CCC-SLP Support Services Coordinator kkublin@cornerstonelc.com December 2011 Cornerstone Learning Community, Kublin (2011)
  • 2. Agenda  Introduction  Reading the score sheet  Placing scores in context  Questions Cornerstone Learning Community
  • 3. What is the Iowa test?  A norm-referenced test developed by the University of Iowa  tests mastery of the academic skills found in the elementary curriculum  has been used across the nation in similar form since 1935, and is supported by research and documentation Cornerstone Learning Community
  • 4. Standardized testing sameness – others have taken the same test under the same conditions scores can be compared from one time to the next and among students and groups scores of individuals can be combined meaningfully to describe group performance administered at CLC in fall to students grade three through eight represents a “snapshot” of a student’s performance at a specific time. Cornerstone Learning Community
  • 5. ITBS Core Subtests Reading Math Problem Reading Concepts & Solving & Computations Vocabulary Comprehension Estimation Data Interpretation Language Usage & Spelling Capitalization Punctuation Expression
  • 6. Reading the score sheet Cornerstone Learning Community
  • 7. Types of Scores that appear ona Student Report Standard Score (SS) Grade Equivalent (GE) National Stanine (NS) National Percentile Rank (NPR)
  • 8. Standard scores Used to convert raw scores into numbers that can be compared Describes a student’s location on an achievement continuum Compares individual performance to the normed sample Cornerstone Learning Community
  • 9. Grade Equivalent (GE) A decimal number that indicates the grade level and the months (e.g. 3.2 would indicate a third-grade level in the second month). GE’s indicate what the average student in the indicated level would achieve if given the same test.
  • 10. GE-Example Example: My 4th grade child received a 6.3 GE in math computation. This indicates that her score is like the one a typical student in the third month of 6th grade would likely get on that same test.
  • 11. Grade Equivalent (GE) GE does not indicate a student’s instructional level. GE allows for comparison of growth over time.
  • 12. GE Growth ComparisonsLow Performing student – less than 20 months gain in two yearsEX: Fall grade 5 – 4.2 Fall grade 7 – 5.6Average Performing student – about a 20 month gain in two yearsEX: Fall grade 5 – 5.2 Fall grade 7 – 7.2High Performing student – more than 20 month gain in two yearsEX: Fall grade 5 – 6.2 Fall grade 7 – 8.8
  • 13. Stanine Scores Stanine scores show a student’s relative position in a group of students who took the same test at the same time of year nationally. The (standard nine) stanine method ranges from a low of 1 to a high of 9 and has an average value of 5;  1,2 or 3 is below average  4,5 or 6 is average  7,8 or 9 is above average Stanines are a convenient way to identify areas of strength and weakness in a set of test scores. They are less precise indicators than the detailed NPR’s.
  • 14. Stanine Cognitive Level S Very High 9 Above Average 7&8 Average 4, 5, & 6 Below Average 2&3 Very Low 1 Cornerstone Learning Community
  • 15. Stanine- Example My 5th grade son received a stanine score of 6 in his Math Total score. This means that out of the group of students that took the same test he performed within the average, but at the high end of the average.
  • 16. National Percentile Ranking(NPR) This is an indication ranging from 1 to 99 showing what “percentile” your childs score corresponds to in relation to others taking the same test. This is NOT the percent correct.
  • 17. Nat’l Percentile Rank (PR) Achievement NPR Level Very High 96-99 Above Average 76-95 Average 25-75 Below Average 5-24 Very Low 1-4
  • 18. NPR - Example My 7th grader scored in the 89th percentile in Reading Comprehension. This means that she scored higher than approximately 88 percent of 7th grade students on whom the test was normed.
  • 19. How stanines and PR line up Stanines Pecentile Ranks 9 96 and up 8 89-95 7 77-88 6 60-76 5 40-59 4 23-39 3 11-22 2 4-10 1 Below 4 Cornerstone Learning Community
  • 20. How teachers use the results• To understand individual profiles of students• To evaluate group strengths and needs• To look at long term curriculum strengths and development opportunities Cornerstone Learning Community
  • 21. Validity Testing conditions Amount of experience with standardized tests, particularly the timed component Individual variables Cornerstone Learning Community
  • 22. Why Test? To provide insight into the relative strengths and weaknesses in specific subject areas To monitor student progress over time To identify areas for enrichment or remediation in differentiating student instruction
  • 23. 2011 Results by Grade Levelcompared to nat’l school norms Reading Language Math Core TOTALGrade 3 97 81 76 92Grade 4 99 80 93 94Grade 5 99 99 84 98Grade 6 90 99 99 99Grade 7 99 93 96 96Grade 8 99 99 97 99 Cornerstone Learning Community
