Generally speaking, there is no specific age limit for teachers' resignation policy, but it is determined according to the contract between teachers and schools and local laws and regulations.

If there are specific resignation clauses in the contract signed between the teacher and the school, then the teacher needs to resign according to the provisions in the contract. If there are no specific regulations, then teachers need to abide by local laws and regulations, such as labor law and labor contract law.

Teachers need to inform the school in advance when they resign, and they need to go through relevant procedures and processes in accordance with regulations, such as filling out resignation application forms, returning work certificates, and settling wages and benefits. At the same time, if there are any disputes between teachers and schools, they can be solved through legal channels.

It should be noted that teachers over the age of 45 may face some special problems and challenges when they resign, such as difficulties in re-employment and providing for the elderly. Therefore, before resigning, teachers are advised to consult relevant legal professionals or local education departments to understand local policies and regulations, so as to better cope with possible problems.
