When should testing for matrix reasoning be discontinued?

Discontinuation of testing for matrix reasoning is appropriate after three consecutive scores of 0. This policy is based on the premise that if a child is unable to answer three items correctly, it indicates that they may not have the requisite understanding or ability to complete the task effectively. The rationale is that continuing to test beyond this point is unlikely to yield useful information about the child's abilities and can lead to frustration for both the tester and the child. Therefore, stopping after three zero scores helps to ensure that the testing process remains efficient and respectful of the child’s capabilities and emotional response.
