The WJ IV is the perfect assessment for accurately screening, diagnosing, and monitoring progress in reading, writing, and maths achievement areas. The UK and Ireland edition is a special edition of the WJ IV which has been designed and adapted from the WJ IV Tests of Achievement,  Form C. While the norms have not changed, all of the content has been anglicised for use in the UK and Ireland and the testing battery has been shortened from 20 tests (standard and extended battery tests available in the full Wj IV) to the 11 core tests (standard battery only) thus making it more economical, affordable, and accessible to those schools and examiners seeking out a reliable and robust assessment tool.

Examiners can choose to administer all 11 subtests or can select individual subtests for isolated use. The WJ IV will allow examiners to gain an in-depth understanding of a person’s academic strengths and weaknesses enabling targeted interventions to be put in place. Scores from the WJ IV can also be used to apply for access arrangements in the UK. With 11 subtests (see table below), spanning a huge age range (4- 90+ years) and assessing areas of early literacy and early number skills as well literacy and maths, the WJ IV is the perfect choice for students in every educational setting.
