The GED® Science Test focuses on the fundamentals of science reasoning, striking a balance of deeper conceptual understanding, procedural skill and fluency, and the ability to apply these fundamentals in realistic situations. In order to stay true to this intention, each item on the Science Test is aligned to one science practice and one content topic.

The science practices can be described as skills that are key to scientific reasoning in both textual and quantitative contexts. The science practices are derived from important skills enumerated in the Career and College Ready Standards as well as in The National Research Council’s Framework for K-12 Science Education.
