Introduction

Children and teens engage in many different online activities: gaming, messaging, sharing posts, and attending remote lessons. Not every activity carries the same risk. This article offers a simple, repeatable method to quickly assess the risk of a specific online activity and help decide proportionate actions.

Why use a method?

Without a method, responses tend to be emotional or inconsistent: either blocking everything or accepting too much risk. A method helps compare activities, explain choices to children and colleagues, and create clear rules.

Key concepts (plain language)

  • Probability: how likely it is that an activity will lead to a problem (for example contact with strangers, data exposure, inappropriate content). Rate it 1–5 (1 = very unlikely, 5 = very likely).
  • Impact: how serious the effect would be if the problem occurred (embarrassment, reputational harm, physical safety). Rate it 1–5 (1 = negligible, 5 = severe).
  • Risk: a simple product Probability × Impact. Scores range 1–25. Higher scores mean more urgent action.

Step-by-step method (quick)

  1. Define the activity: describe what happens (e.g. “class messaging app use”).
  2. Identify main risks: list 2–4 specific risks (e.g. contact with strangers, photo sharing, misinformation).
  3. Assign Probability (1–5) for each risk.
  4. Assign Impact (1–5) for each risk.
  5. Calculate Risk = Probability × Impact.
  6. Aggregate (optional): sum scores or consider the highest score to decide action.
  7. Choose the response: no action, light mitigation, active control, or temporarily prohibit.

Suggested thresholds

  • 1–5: low risk — inform and monitor casually.
  • 6–10: moderate risk — set clear rules, time limits, filters or occasional supervision.
  • 11–15: high risk — require specific procedures, privacy settings, parental approval and regular supervision.
  • 16–25: critical risk — disallow or allow only with strong controls and direct supervision.

Practical examples (family context)

Example A — Posting a birthday party photo publicly

  • Identified risk: exposure of images and personal data.
  • Probability: 3 (moderately likely).
  • Impact: 4 (possible misuse of images).
  • Risk: 12 → high. Action: make the post private, obtain consent, remove metadata, explain why.

Example B — Online game with voice chat with strangers

  • Identified risk: contact with unknown adults and inappropriate language.
  • Probability: 4.
  • Impact: 3.
  • Risk: 12 → high. Action: enable privacy settings, limit play to friends, shorten sessions, supervise.

Practical tools and short checklist

  • Quick template (1 minute): Activity name / Main risk / Prob (1–5) / Impact (1–5) / Action.
  • Family rules: minimum ages, daily time limits, approved app list, banned behaviours.
  • Settings: privacy controls, private accounts, content filters, passwords shared only with caregivers.
  • Communication: clear explanations and repeated reminders about why rules exist.

Explaining decisions to children and adolescents

  • Use simple language: explain risk as the chance of a problem and how serious it could be.
  • Involve them: ask for their view and offer safer alternatives.
  • Be transparent: explain rules and give clear steps on who to contact if something goes wrong.

Adapting the model for schools

  • Apply it to school activities (teaching platforms, sharing student work online, collaborative projects).
  • Involve staff: name a person responsible for assessments and keep a decision log.
  • Issue simple guidelines: a short form for each activity and clear communication to families.

Limitations

  • It relies on human judgment: be conservative when uncertain.
  • It is not a replacement for technical risk assessments for advanced threats (e.g. targeted attacks).
  • Reassess periodically: the digital context changes, so review decisions every 6–12 months.

Conclusion and quick recommendations

  • Use Probability×Impact to make consistent, quick decisions.
  • Prefer proportionate measures: the higher the score, the stronger the measures.
  • Document decisions and communicate them clearly to children, families and colleagues.

This method turns emotional reactions into informed, repeatable choices that work in the family and classroom alike.
