Wechsler Intelligence Scale for Children - Fifth Edition (WISC-V) Competency Practice Test

The Digit Span Forward subtest (DSf) of the WISC-V measures attention and working memory by requiring children to repeat a series of numbers in the same order they were presented. The maximum raw score in this subtest is determined by the longest sequence of digits that a child can accurately repeat, along with the number of sequences correctly completed.

In the WISC-V, the testing typically starts with a sequence of two digits, and additional digits are added until the child can no longer repeat the sequence correctly. The maximum raw score for DSf is achieved when a child successfully completes all possible sequences, which totals to 18 points. This scoring reflects a comprehensive assessment of a child's ability to manipulate and recall numerical information in a forward format, reinforcing the importance of digit span not only in cognitive evaluation but also in understanding attention capacities in children.

Thus, the correct answer, which is 18 points, represents the upper limit of what can be achieved in the Digit Span Forward task.
