Thailand hiring season

I’ve sent a few applications off for primary teaching positions in Thailand this Dec/Jan. I’ve only received one interview and missed out on that position. I’ve got all relevant qualifications and plenty of experience in the UK and abroad. I also have a ‘trailing’ spouse (Thai) and 2 dependents. Although I don’t think they’re technically a trailing spouse as a Thai national.

Is it too early to assume I’m not going to find anything this year? When does the hiring season end? Will schools not hire teachers with a spouse and 2x dependents?

Thanks in advance for your input.
