Every teacher applicant arrives with reference letters describing them as excellent, hardworking, and punctual. Almost no reference letter has ever said otherwise — which is why letters alone are nearly useless. A teacher reference check done properly is a short, structured phone call with a former principal or supervisor, asking specific questions that a polite letter will never answer. In a sector where one bad hire affects hundreds of children, those ten minutes are among the highest-value minutes in your hiring process.
This guide covers who to call, what to ask, how to spot a fake reference, and what to do with uncomfortable answers — all in the practical context of Pakistani school hiring.
Why Calls Beat Letters
Letters are written to help the candidate, often by someone who barely supervised them. A call, by contrast, lets you hear hesitation, ask follow-ups, and probe specifics: "Would you rehire this teacher?" is a question no letter answers honestly, but a pause on the phone tells you plenty. Former employers are also more candid verbally, especially when you promise the conversation stays confidential and you ask about facts (dates, subjects, attendance) before opinions (quality, character).
Calls also catch inconsistencies. A CV claiming three years at a school, contradicted by a former principal who says the teacher left after one term, is a serious finding — and one that a letter would never reveal. Always call before the final offer, never after; discovering a problem after the teacher has started is a far harder conversation.
Who to Call — and How to Reach Them
Ask the candidate for two professional references: the most recent principal or academic head, and one other supervisor or senior colleague. Do not accept only personal references (a relative, a friend) for a teaching post. Find the school's number independently — from the school's website, Facebook page, or directory — rather than calling only the number the candidate supplied, which could belong to anyone. If the school is small or closed, try the former principal's current school.
Introduce yourself clearly, explain you are verifying a reference for a teaching position, and ask for five to ten minutes. Reference calls come after the demo lesson in the teacher recruitment process — never as a substitute for it. Most principals will help, because they know they will want the same courtesy one day. If a former employer refuses to comment beyond confirming dates, that itself is information — note it neutrally rather than treating it as a negative.
The Questions That Reveal the Truth
Start with facts: dates of employment, subjects and classes taught, and the reason for leaving as the school understood it. Then move to performance: How was the teacher's classroom management? How did they handle parents? Were lesson plans submitted on time? Was attendance reliable — any pattern of late arrival or unexplained absence? Then the two most revealing questions: "Would you rehire this teacher if a vacancy opened?" and "Is there anything I should know before placing this teacher with children?" Ask the second question plainly and then stay quiet; silence is where honest answers emerge.
Also ask about strengths in the same breath: what was this teacher genuinely good at, and in what kind of class did they thrive? A teacher who struggled with a large senior class may be excellent with junior sections — and that distinction could make them the right hire for your vacancy rather than a rejected one. Listen for specifics: "She turned around our Class 5 English results" is credible; "She was good" is not.
Verifying the Reference Itself
Reference fraud exists: candidates occasionally supply a friend's number as a "former principal." Protect yourself by verifying the school independently, checking that the referee's role matches what the candidate claimed, and asking the referee one detail only a real supervisor would know — for example, which section the teacher taught, or who headed the school that year. If the referee cannot answer basic questions about the school, be suspicious. Also verify qualifications separately: degrees and B.Ed. certificates can be checked with the issuing institution, and experience letters should match the dates the referee confirms.
Be careful with privacy and fairness. Verify only job-relevant information, keep notes confidential, and never share one school's reference comments with another. A reference check is a professional verification, not gossip — handle it that way and other schools will keep taking your calls.
Warning Signs That Stop a Hire
Stop or pause the hire if: dates on the CV do not match the referee's account; the candidate cannot produce a real supervisor reference at all; two referees give contradictory accounts of the same period; a former employer declines to rehire and hints at conduct concerns; or the candidate becomes evasive or hostile when you say you will call references. Any single item may have an innocent explanation — ask the candidate about it directly before deciding. But two or more together form a pattern, and patterns should end the process.
Child safety deserves special care: if any reference raises a concern about a teacher's conduct around children, do not proceed without a thorough, documented review, and consider guidance from your school's child-protection policy — see our guide to child protection policies in schools. When in doubt, choose the safer candidate; there will be other applicants, but there is no second chance with a child's safety.
The Two Questions That Matter Most
Recording and Using What You Learn
Keep a short written record for each reference: referee name and role, date of call, facts confirmed, and a summary of opinions — stored confidentially in the hiring file, not circulated among staff. Use the findings alongside the demo lesson score and interview notes, not as a veto in isolation: a mediocre reference plus a weak demo is a clear no, while a strong demo plus one lukewarm reference may simply mean the teacher and that school were a poor fit. Tell the candidate the outcome promptly either way; a teacher treated fairly in your process may reapply, and will speak well of your school regardless.
Reference checks also complete the hiring sequence properly: ad, screening, interview, demo, references, offer — in that order. Skipping the reference step to save ten minutes is the most expensive shortcut a school can take. For the step that follows a successful check, see our new teacher onboarding guide.
