Not necessarily. Whether the on-the-job master's thesis should be evaluated externally or blindly, or both, that is, double evaluation, depends on the school regulations. Some schools only need one kind of audit, while others need two kinds.

To participate in thesis defense, on-the-job graduate students need to submit an application for thesis defense to the school within the specified time. The school conducts blind evaluation on in-service graduate thesis. After revision by the tutor, the school will check the papers of in-service graduate students twice. However, if the paper fails, you can't take part in the paper inspection. In addition to the tutor's review, the school will also arrange a unified review of the master's thesis. The way to review is blind review, but not all master students.
