The book presents methods for judging what tests really measure, not just how they score. It shows how correlations with ratings of industrial ability, educational attainment, and social fitness can guide diagnosis and treatment. Throughout, it discusses the value of combining tests to capture a fuller picture of a person’s strengths and challenges.

How validity is demonstrated through experience, case histories, and group correlations.
Why Porteus tests can complement other batteries like the Binet to improve diagnoses.
What army performance tests reveal about social functioning and practical abilities.
How educators and clinicians use test results to forecast outcomes and tailor support.

Ideal for students, clinicians, and researchers seeking a grounded view of how cognitive tests relate to everyday functioning.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
