CGMs at School: A Parent’s Guide to Teachers, Tech Rules & Tackling T1D Like a Pro!

Sending your child with Type 1 Diabetes (T1D) to school can feel daunting, especially when introducing a Continuous Glucose Monitor (CGM) into the mix. While CGMs offer incredible benefits- fewer finger pricks, real-time glucose tracking and better overall management- many schools may be unfamiliar with them.

From educating teachers and caregivers to handling schools with strict no-phone policies, this guide will help you ensure your child’s CGM is used effectively and that school staff feel confident in supporting their diabetes management.

What is a CGM and Why Does it Matter in School?

A CGM tracks glucose levels 24/7, sending updates to a phone, receiver or smartwatch. This helps spot patterns, predict lows before they become serious and reduce the need for frequent finger pricks.

For school-age children, a CGM can mean:

• Fewer classroom disruptions for blood sugar checks

• Better management during PE, lunch and break time

• Increased independence in diabetes care

• Peace of mind for parents and teachers

However, teachers and caregivers may not be familiar with CGMs, and some schools have strict no-phone policies, making access to real-time readings tricky. That’s why clear communication is key.

How to Educate Teachers & Caregivers about CGMs

Most teachers understand the basics of Type 1 Diabetes, but many won’t know how a CGM works or what to do when it beeps. Here’s how to educate school staff and ensure your child gets the support they need.

1. Start with a Simple Explanation

Teachers don’t need a detailed medical briefing- they just need to understand what a CGM does and how to respond to alerts.

Here’s a simple script you can use:

“A CGM tracks my child’s glucose levels and alerts us when they’re too high or too low. The readings are sent to a (phone/receiver/smartwatch), allowing us to manage their diabetes more easily. It helps us avoid serious lows and highs, keeping them safe and able to focus in class.”

2. Provide a CGM Cheat Sheet

A one-page, easy-to-read CGM guide can be a game changer for busy teachers. Include:

• How a CGM works (brief overview)

• What the CGM arrows and alerts mean (and how to respond)

• When a child might still need a finger prick

• Emergency contacts

• Where diabetes supplies are kept

3. Explain CGM Alerts & What to Do

Many teachers worry about CGM alarms disrupting class. Let them know:

• Most CGMs vibrate before sounding an alarm

• Your child may be able to manage alerts independently

• When an alert needs immediate action (e.g. a low glucose alarm)

If necessary, set clear guidelines about when your child can check their CGM and when they should ask for help.

4. Address Common Teacher Concerns

• “Will CGM alarms be distracting?”- CGMs can be set to vibrate first. Most children learn to manage alerts quietly.

• “Does the child still need finger pricks?”- Sometimes! CGMs aren’t always 100% accurate, so backup checks may be needed.

• “What if the sensor falls off?”- Show teachers what the sensor looks like and where to find a spare if needed.

5. Arrange a Meeting with Key Staff

A quick 10 minute chat at the start of term with teachers, TAs, the school nurse and lunchtime staff can make all the difference.

Navigating Schools with No-Phone Policies

Some schools ban mobile phones in class or only allow “brick” phones on school grounds, which can be a challenge if your child’s CGM readings are sent to an app. Here’s how to work around these rules while ensuring safe diabetes management.

Option 1: Request a Medical Exemption

Many UK schools allow phones for medical reasons if you provide:

• A doctor’s letter explaining why the phone is needed

• A Section 100 Medical Conditions Policy request (under the Children and Families Act 2014)

• A Health Care Plan (HCP) outlining how the CGM helps manage diabetes

Most schools will allow your child to keep their phone on silent (vibration) in their bag or pocket for CGM use only.

Option 2: Use a CGM Receiver Instead

If your child’s school won’t allow a phone, check if their CGM has a standalone receiver. Some CGMs (like Dexcom and Freestyle Libre) can work without a phone.

Option 3: Use a Smartwatch

If the school allows smartwatches, your child may be able to view CGM readings on their wrist instead of using a phone. This can be a great compromise.

Option 4: Set Up a Teacher or TA to Monitor Readings

Some parents set up the Dexcom Follow app on a school iPad or a teacher’s phone so staff can help monitor glucose levels. This can be useful for younger children.

Option 5: Plan for Manual Checks

If phone access is completely denied, work with the school to create a plan for:

• Set blood sugar check-in times

• Where and when a child can check their CGM manually

• What to do if symptoms don’t match CGM readings

Managing CGMs During PE, Lunch & Break Times

These are high-risk times for blood sugar fluctuations, so it’s crucial to have a plan in place.

For PE & Sports

• Exercise can cause blood sugars to drop- staff should allow CGM checks before, during and after activity

• Keep a hypo kit (gluco tabs, juice, snacks) nearby

• If possible, allow children to wear CGMs and smartwatches during sports

For Lunch & Snacks

• Lunch staff should understand carb counting and insulin timing

• If your child’s meal changes unexpectedly, they should be allowed to check their CGM before dosing insulin

• Ensure they have access to hypo treatments, if needed

For Break Time & Playground Supervision

• Playground staff should know what a hypo looks like and when to intervene

• Children should be allowed to carry glucose tablets or a small hypo kit in their pocket

• CGMs should be checked before and after playtime, as activity can cause unexpected drops

Final Tips for a Smooth School Experience

• Keep communication open- Regular check-ins with teachers and school staff can help troubleshoot any issues.

• Teach your child to self-advocate- As they grow, they should feel comfortable explaining their CGMs to teachers and asking for what they need

• Update the school if things change- If your child’s CGM settings or management plan changes, keep the school informed.

With the right support and preparation, a CGM can make school life safer and easier for children with Type 1 Diabetes. Educating teachers, working around tech policies and having a solid plan for daily school activities will help ensure your child thrives both in the classroom and the playground.
