CLT's LockDown Browser

To protect the integrity of the CLT and CLT10, and ensure a fair testing experience for all students, we’re introducing a secure LockDown Browser. This simple tool helps prevent cheating and ensures that every score truly reflects a student’s own ability. It’s an important step in maintaining the high standards that make the CLT and CLT10 trusted, respected assessments—while still keeping things smooth and stress-free for schools and families.
