Is a criminal record check required when applying for a Thai Ed visa through a language school?

When applying for an Educational (Ed) visa to attend a Thai language school, there is a section on the application form asking if the applicant has a criminal record. While some users indicate that this question is not routinely enforced and that schools may not check criminal histories, others suggest that for certain visas, a criminal record check might be necessary and that it can involve verification with the applicant's home country. Therefore, honesty in completing the application is advised.
