Woodcock-Johnson Psycho-Educational Battery-Third Edition Descriptive Essay by Peter Pen

This paper explains that the Woodcock-Johnson batteries (WJIII), which was first published in 1977, is a comprehensive test battery used for assessing cognitive and academic achievement skills in individuals, aged 2 years through 90 years. The author points out that WJIII norms are based on data from the same sample of subjects, which allows direct comparisons among and within a subject's scores, giving a degree of accuracy not possible when comparing scores from separately normed tests. The paper stresses that professionals who use the WJIII ACH are responsible for maintaining test security by carefully storing materials and protecting test contents. The author would use this testing system to understand a student's strengths and weaknesses because it has more validity than other tests, is easy to give, is current and shows strong reliabilities.
