First edition, Second edition and third edition. And after that, we go in detail about the second edition of his Achievement Test. First, we should know the definitions of a few words Achievement: available knowledge (especially in a particular subject), proficiency, or skill. The term is most commonly used in the sense to mean academic achievement.[6] Test: any standardized instrument, including self-report inventories, reports, used to measure behavior or mental attributes, like attitudes, emotional, cognitive abilities, functioning, and cognitive abilities (reasoning, comprehension, abstraction, etc.), interests, values, and personality characteristics.[7] "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION Literature review: Who is Weschler? Dr. David Wechsler, A Jewish Psychologist, was born in a Jewish family in Lespezi, Romania. He studied at the City College of New York and Columbia University, where he earned his master's degree in 1917 and his Ph.D. in 1925. During World War I, he worked with the United States Army and frontlines to make and develop a psychological test to screen new draftees while studying under Karl Pearson and Charles Spearman. His tests are "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION worldwide used and are “Wechsler Adult Intelligence Scale (WAIS)” “Wechsler Preschool and Primary Scale of Intelligence (WPPSI) in 1967.” “Wechsler Intelligence Scale for Children (WISC) in 1949” He died on May 2, 1981.[4] "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION What is the WIAT first edition? The “WIAT” stands for the Wechsler Individual Achievement Test. An achievement test measures how an individual is doing in areas of academic work or school work. The WIAT give a summary of marks in most common school subjects like math, reading, written languages, and oral languages. commonly, to the WISC, an average score is 100, above this average means above average functioning in above subjects, and below is below average. “The age range is wide, starting at 4 years to 19 years old”.[1] "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION What is the WIAT Second Edition? It was developed in 2002, and is the latest version of the first edition, The Wechsler achievement test (WIAT). Not like the first edition, The WIAT-II can be administered to individuals aged 4–85 years [3] The Wechslers Individual Achievement Test. Second-Edition (WIAT-II; Wechsler, 2005). assesses the academic achievement of children, adolescents and college students and adults, ages from 4 through 85. The test enables the assessment of a big broad range of academic’s skills and only a specific area of need. The WIAT-II is a revision for the original WIAT (The Psychological Corporation), and some additional measures. There are four main scales: Reading, writing, math, and Oral Language. inside these scales, there are a total of 9 sub-test scores "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION What is the WIAT Third Edition? There are a small number of differences between the versions of the subtests in the UK and US. These include changes to the picture items, replacing of Americanisms and spelling differences. The WIAT-III US edition was published in 2009. and for use with those who aged 4 through to 50 years. It includes 16 subtests divided between in all areas of Oral Reading, Math Fluency and Early Reading Skills.[5] "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION The Test Subject Areas There are four areas of intelligence, they are different, that are tested by the WIAT. They are reading, math, written language and oral language. Each of these areas, is broken down for testing purposes. The math area, for example, is broken down into two sub-tests, numerical operations and math reasoning. The reading section will cover comprehension of reading and word reading. Spelling and written, are both sections in the written language area, and oral expression and listening comprehension are covered, under the oral language area. "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION 1) Reading Word Reading: assesses pre-reading (phonological awareness) and decoding skills (naming letters, phonological skills [working with sounds in words], reading words from lists). Reading Comprehension: assesses types of reading comprehension skills taught in the classroom or used in everyday life (matching words to pictures, reading sentences aloud, orally answering oral questions about reading passages, silent reading speed). Pseudoword (phonetic) Decoding: assesses the ability to apply phonetic decoding skills. (Reading nonsense words aloud from a list [phonetic word attack]). "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION 2) Math Numerical Operations: evaluates the ability to identify and write numbers ( e.g. counting, and solving paper & pencil computations). Math Reasoning: assess the ability to reason mathematically ( e.g. counting, identifying shapes, and solving verbally framed "word problems" [presented both orally and either written or in illustration]). 3) Written Language Spelling: evaluates the ability to spell (written spelling of dictated letters, sounds and words that are read in sentences). Written Expression: assesses the writing process (writing letters and words as quickly as possible, writing sentences, and writing a paragraph or essay). "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION 4) Oral Language Listening Comprehension: measures the ability to listen for details (multiple-choice matching of pictures to spoken words). Oral Expression: assesses general ability to use oral language effectively (repeating sentences, generating lists, describing scenes and pictured activities).[8] "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION Looking at the Scores When the WIAT is scored, there will be a set of numbers that will be given to the exam taker (test taker). The average score for people who take the test is 100, and any score from 90 to 109 means that it’s in the average intelligence range. Scores from 110 to 119 are meant to be High Average. Superior, are the ones who their score range is from 120 to 129. anything over score of 130 is considered Very Superior. These scores will help to indicate that where a student might excel and be good when in school. On the other side, scores from 80 to 89 are considered to be Low Average, scores from 70 to 79 are called Borderline and any score below 69 is considered as Extremely Low. These scores can help us to identify areas in which the student may struggle. "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION Other Scores You May See Finally, though, the above scores are the common main scores that everyone looks for, there are also other types of scores that will be given with the results of the WIAT. For example, you will likely see a score labeled as “Percentile Ranking”, or “PR”. This is given in a percentage and shows how the test taker scored amongst and against his or her peers. For instance, if there is a 60 in this area, you will know that they did better than 60 percent of the other test takers. Other scores are Age Equivalent and Grade Equivalent scores. These will show you where the test taker ranks by age and grade. For example, if you have a 12-year-old taking the test, they may get an age equivalent of 13 or 14 instead of 12. For grades, an 8th grader may score in the 7th-grade range which may indicate more focus in certain areas is needed.[2] "WECHSLER INDIVIDUAL ACHIEVEMENT TEST-SECOND EDITION Conclusion: The WIAT-II is a wonderful way to understand where someone might excel and where they may have difficulties and ultimately can be a great tool to help set educational and lift goals. And it also helps us to predict a near future of the individual.
