Gr 7 Up—Comprehension and vocabulary tools stand out in this series to help readers navigate the text. Key icons and "Words to Understand" for each chapter are offered up front and reappear in the text in red font. Vocabulary reinforcement is welcome, as a litany of medical terms can hinder even fluent readers. The wealth of titles offered also allows an in-depth look at specific jobs as well as extra details, such as an explanation of the pathology of asthma, with graphics of restricted airways, in Respiratory Therapists. Anecdotes might describe a patient or experience during a day on the job, and QR codes send readers to Internet videos to elaborate on a topic. Questions at the end of each chapter are thought-provoking, such as what a professional trainer should do if an injured athlete wants to continue a game. Clear language, bullet lists, and captioned photos are close-up and relevant to the tools, environment, and tasks. VERDICT Comprehension boosters, QR codes, and depth of coverage make this a top choice for high school collections.
