What does 'security of tenure' mean for public school teachers under RA 4670?

• A. Protection from arbitrary dismissal and the right to due process in disciplinary actions.
• B. Automatic promotion every two years.
• C. Lifetime tenure regardless of performance.
• D. Exemption from any disciplinary actions.

Answer: (A)

Security of tenure means teachers are protected from being dismissed without a fair reason and without due process. Under RA 4670, a public school teacher cannot be dismissed or suspended except for just causes, and any disciplinary action must follow due process—formal charges, proper notice, an opportunity to defend oneself, a hearing, and a fair decision. This gives teachers employment stability while keeping accountability intact. It is not about automatic promotions, it does not guarantee lifetime tenure regardless of performance, and it does not exempt teachers from disciplinary actions.
