In-school testers taking the CLT must remain for the full test, per in-person proctoring requirements, even if they finish the test early.
At-home testers (remotely-proctored CLT and at-home CLT8s and CLT10s) may finish a section early if they’ve completed it before the allotted time has elapsed. Students may not return to an earlier portion of the exam if they finish a section early.
