6 WISC V Spanish in a nutshell Developed on children whose primary language is Spanish ages 6:0 16:11, and who have attended schools in the US for up to 5 consecutive years Equated to the English edition using IRT & equal percentile approaches Updated norms based on a representative sample of 2,200 children aged 6:0 16:11 Normative sample stratified to match current U.S. census data based on sex, race/ethnicity, parent education level, and geographic region for each age group Includes additional reliability and validity evidence based on Spanishspeaking clinical and validity samples 16 WISC V Spanish The Sample The Norms Adjusted Scores 17 Same Meaning 18 6

7 Equated Subtests VCI (Sim, Voc, Info, Comp) WMI/AWMI (Digit Span, Picture Span, Letter Number) 19 What does this mean? That the scores mean the same, regardless of whether child is tested with the WISC V or the WISC V Spanish. Norms tables are already equated no need for additional formulas or manual conversions. 20 From the WISC V Spanish Manual: "With WISC-V Spanish you can test Hispanic children in Spanish and compare their performance to all children the same age living in the United States. This is accomplished in two ways. For subtests unaffected by the translation, such as Block Design, the WISC-V norms are applied directly to the WISC-V Spanish. For subtests affected by the translation, such as Vocabulary, the WISC-V Spanish raw scores were statistically equated to the WISC-V raw score distributions before applying the WISC-V norms. These equating adjustments are built into the WISC-V Spanish raw to scales score tables for ease of use. Thus, you can confidently test Hispanic children in Spanish and compare their cognitive ability to all children, regardless of whether they speak Spanish or English." 21 7

8 Adjusted Scores What do we adjust? The Verbal Subtests (SI, VC, IN, CO), and the corresponding index scores: VCI and VECI 22 What do we adjust by? Various linguistic, educational, and living environment variables 23 Questionnaire Eng & Spa Examiner may NOT edit Matches digital format 24 8

9 How do we adjust? Through a series of regression equations. Adjusted scores only on Q-i and Q-g only. ***If answers are missing, may not get all scores.*** 25 Caveats * Not normative data * No representation of intellectual ability * Parental report, subjective * Not yet validated for Sped eligibility * Must not try to interpret in isolation! 26 Interpretative Statements Page 183 of Manual Adjusted all higher than Obtained (Normative): The child appears to be performing verbal comprehension tasks in Spanish better than what might be expected given the amount of support for Spanish language development and usage in his/her environment 27 9
