Updated April 2026
We’ve launched the updated Traffic Lights® which offers more guidance about responding to sexual behaviours and supports you to understand a broader range of behaviours, including digital ones.
If you previously enrolled in our e-learning, you will be able to access the new version for the remainder of your access period.
To support professionals who have trained historically on our tool, we have created a condensed refresher training to bring your staff up to speed in just 60 minutes.
Sexual behaviours are categorised as green, orange or red light and are broken down by age group.
The framework will help you identify whether behaviours such as kissing, touching genitals, masturbating, lifting another child’s skirt, drawing sexually explicit artwork are a cause for concern and what you can do.
Green light sexual behaviours are typical and developmentally appropriate.
They are:
These behaviours provide opportunities to talk, explain and provide support.
Orange light sexual behaviours cause concern because of:
These behaviours should not be ignored and signal the need to monitor and provide targeted support.
Red light sexual behaviours indicate or cause harm because they are:
These behaviours signal the need to provide immediate protection and follow up support.
Training is required before being able to access the framework to ensure you are equipped to safely and confidently use it. We have various training options including group training, licenses and e-learning.
After completing the Traffic Lights® training which is CPD-certified, you will be able to:
✅ Recognise and identify sexualised behaviours and differentiate between those which are part of healthy sexual development and those which are problematic or harmful. ✅ Reflect on your own values and understand how they can impact on decision making. ✅ Demonstrate a common language around developmental and harmful sexual behaviours. ✅ Understand what a behaviour may be communicating and why the child or young person may be exhibiting the behaviour. ✅ Appropriately respond to sexualised behaviours, considering possible motivations, communications and severity.
97% of people who have been trained on the framework are more confident as a result of the training and developed useful skills for their practice.
95% of learners rate their overall experience as ‘good’ or ‘very good’.
We offer many different training options, whether you want to train when it suits you or license the framework to upskill your entire organisation. Once you’ve completed the training you’ll get access to the Traffic Lights®. framework.
Complete the training at your own pace and in your own time on our online learning platform. Once the training is complete, you’ll be able to access the framework.
