6 Reasons Schoolchildren Lie or Steal (and What Parents Can Do With Teachers)

6 Reasons Schoolchildren Lie or Steal (and What Parents Can Do With Teachers)

Lying and stealing can show up in elementary, middle, and high school for many reasons—some impulsive, some social, and some rooted in stress. The most helpful first step is to look at what happened at school, who was involved, and what your child was trying to avoid or gain.

This guide focuses on school situations: classmates, classroom rules, group chats, lockers, lunchrooms, and after-school activities. For a deeper look at general causes across ages, see Why do children tell lies. Causes of lying in kids.

Before you react: a quick school-incident snapshot

• What exactly happened? (item taken, story told, rule broken)
• Where and when? (hallway, recess, online, after practice)
• Who was involved? (one friend, a group, older student, teacher)
• What was the “payoff”? (fit in, avoid trouble, get an item, save face)
• What’s the impact? (harm done, trust broken, safety concern)

The 6 most common school-based reasons kids lie or steal

1. Peer pressure and “bad influence”
   At school, social status can matter more than consequences. A child may lie to match the group’s story (“We were all in the bathroom”) or steal to prove loyalty (“Take it—everyone does”).

   What parents can do (with school support):

   • Ask for specifics from staff: “Who was nearby?” “Was this part of a trend?”
   • Practice scripts your child can use: “No thanks. I’m not doing that,” or “I’m leaving.”
   • Request a seating change, locker move, bus reassignment, or closer supervision if needed.

2. Protecting a friend (loyalty over honesty)
   Some children lie because they fear being labeled a “snitch,” or because they’re trying to protect a friend from embarrassment or punishment. This can show up as “I didn’t see anything,” even when the child did.

   What parents can do:

   • Teach the difference between privacy and secrecy that harms someone.
   • Role-play how to report safety issues without “tattling.”
   • Ask the school how they handle reporting and confidentiality so your child feels safer telling the truth.

3. Saving face after a mistake (fear of embarrassment)
   Many school lies are “cover-up lies”: missing homework turns into “My teacher lost it,” or a poor grade turns into “The portal is wrong.” Stealing can also be an attempt to avoid embarrassment (taking supplies to avoid looking unprepared).

   What parents can do:

   • Lead with calm facts: “We can handle a bad grade. We can’t handle hiding it.”
   • Help your child make a repair plan: email the teacher, redo work, return items, apologize.
   • Ask teachers for a simple check-in system (planner initials, weekly progress note).

4. Trying to “get what everyone else has”
   A child may steal small items (erasers, snacks, cosmetics, game cards) because peers have them, because they’re traded like currency, or because your child feels left out. Lying may follow: “It’s mine,” or “Someone gave it to me.”

   What parents can do:

   • Talk about classroom norms (sharing bins, community supplies, borrowing rules).
   • Create a low-drama plan for wants: allowance, chores, wishlist, or earning privileges.
   • Coordinate with staff on restitution (returning the item, replacing it, a written apology).

5. Testing boundaries and independence (especially in middle school)
   As kids push for more control, they may lie about where they were at lunch, who they sat with, or what happened online. Sometimes the behavior is less about “being bad” and more about asserting privacy or resisting feeling controlled.

   What parents can do:

   • Set clear, school-relevant boundaries: phones, group chats, after-school locations, curfews.
   • Offer choices within limits: “You can do homework right after snack or after a 20-minute break.”
   • Keep consequences predictable and connected to the behavior (not global punishments).

6. Attention, stress, or feeling unsafe
   Sometimes lying or stealing is a stress response: a child feels overwhelmed, bullied, excluded, or worried about performance and makes a poor choice. In some cases, repeated incidents may signal anxiety, depression, trauma, or another concern that deserves careful follow-up.

   What parents can do:

   • Ask directly (and calmly) about stressors: “Is anyone bothering you?” “What’s the hardest part of the school day?”
   • Request a meeting with the teacher or school counselor to discuss patterns.
   • Focus on skills: coping strategies, problem-solving, and how to ask adults for help.

School scenarios: what to say and do

Scenario 1: “I didn’t take it” (but the item is in your child’s backpack).
Start with facts and a path to repair: “The item is here. Help me understand what happened, and then we’ll figure out how to return it and make it right.” Ask the teacher for the simplest, least-shaming way to return it.

Scenario 2: Your child lies to protect a friend.
Say: “I get that you didn’t want your friend in trouble. At school, honesty is how adults keep everyone safe. Let’s talk about what you can say next time that protects people without covering up harm.”

Scenario 3: Missing homework becomes a big lie.
Say: “We’re going to tell the truth, even if it’s uncomfortable. I’ll help you email the teacher. You’ll complete the work and we’ll set up a plan so it doesn’t spiral again.”

Parent-teacher collaboration checklist

• Share patterns, not labels: “This has happened twice after recess,” not “He’s a thief.”
• Ask for supervision supports: seating, line position, locker area, bus plan, recess monitoring.
• Agree on a restitution plan: return/replace item, apology, classroom repair task if appropriate.
• Plan for communication: one point person, weekly check-in, and what triggers a call home.
• Protect your child’s dignity: request private conversations over public call-outs.

Consequences that teach (instead of escalating)

• Make it right: return, replace, or repair what was taken or damaged.
• Rebuild trust: short-term supervision (checking backpack together, monitored spending).
• Practice the skill: role-play refusing peer pressure; rehearse telling the truth after a mistake.
• Limit high-risk situations temporarily: fewer unsupervised store trips, different ride home, adjusted device rules.

When to seek professional help

Consider extra support if lying or stealing is frequent, escalates despite consistent consequences, involves aggression, or seems tied to distress (sleep changes, intense irritability, withdrawal, panic, self-harm talk, or significant school refusal). Your pediatrician, a licensed mental health professional, or the school counselor can help assess what’s going on and recommend next steps. For general guidance on children’s mental health and when to seek care, families can review resources from the American Academy of Pediatrics and the CDC.

Lying and stealing at school are serious, but they’re also often changeable behaviors when adults respond consistently and coordinate. Focus on safety, restitution, and the skills your child needs to handle peer pressure, mistakes, and stress more honestly next time.
