Which assessments are commonly used to evaluate math skills specific to dyscalculia?

The first choice is correct because Key Math and spatial reasoning tests are specifically designed to assess various mathematic skills and concepts, which can help identify difficulties faced by individuals with dyscalculia. Key Math measures not only basic skills such as number operations but also more complex areas such as problem-solving and understanding of mathematical concepts. Spatial reasoning tests are also relevant as they evaluate how individuals perceive and manipulate objects in space, a skill that is often linked to mathematical reasoning.

The other assessments listed do not target mathematics skills specifically related to dyscalculia. The Peabody Picture Vocabulary Test mainly measures verbal intelligence and vocabulary, not math capabilities. The Wide Range Achievement Test assesses a range of academic skills, including reading and math, but it is not specialized for diagnosing dyscalculia. Lastly, the California Achievement Test provides a general measure of academic skills across subjects but lacks the focused assessment of math skills specific to dyscalculia.
