The role of a mentor in teacher training, and why it matters
When people think about teacher training, they often picture the classroom.
Standing at the front. Planning lessons. Managing behaviour. Gradually finding your feet.
What is less visible, but just as important, is the role of the mentor.
At Portsmouth SCITT, mentoring sits at the heart of the training experience. It is the steady thread that runs alongside everything else, helping trainees make sense of what can sometimes feel like a fast-moving and demanding year.
Learning to teach is not a solo journey
Teaching is complex. It is not just about delivering content, but about making hundreds of small decisions every day.
How do you explain something clearly?
How do you respond when a pupil is disengaged?
How do you adapt when a lesson does not go to plan?
These are not things you simply “pick up” on your own.
A mentor is an experienced teacher who works closely with a trainee throughout their placements. They observe, guide, question and support. They help trainees move beyond simply getting through lessons, towards understanding what effective teaching really looks like.
Turning experience into learning
One of the most valuable aspects of mentoring is the space it creates for reflection.
A lesson might feel like it went well, or it might feel like it did not. In the moment, it can be difficult to know why.
A mentor helps unpick that.
Through regular conversations, trainees are supported to reflect on their teaching, identify what made a difference, and consider what to try next. Over time, this builds confidence and a deeper understanding of practice.
It is this process that turns experience into learning.
“After my first few lessons, I wasn’t always sure what I’d done right or wrong. Talking it through with my mentor helped me see things more clearly and focus on what to improve next.”
From theory to practice
Teacher training is not just about being in the classroom. It is also about engaging with research-informed approaches to teaching.
This is where the relationship between training sessions and mentoring becomes particularly important.
For example, a trainee might attend a session on behaviour, exploring strategies for establishing routines or responding to low-level disruption. Back in the classroom, their mentor can help them apply those ideas in a real context. They might model an approach, observe the trainee trying it, and then reflect together on what worked and what could be refined.
Similarly, during Intensive Training and Practice blocks, trainees focus closely on specific aspects of teaching, such as how to use modelling effectively and questioning to assess. Mentors play a key role in helping trainees practise these techniques, receive feedback, and build them into their everyday teaching.
Without that ongoing support, it is easy for theory to remain just that. Mentoring is what helps it take shape in practice.
“The training sessions gave me the ideas, but it was working with my mentor in the classroom that made them actually stick.”
The balance of support and challenge
Learning to teach can feel overwhelming at times, particularly in the early stages.
A strong mentor recognises this.
They provide reassurance when things feel difficult, but they also know when to push a little further. They ask questions that prompt deeper thinking. They encourage trainees to try new approaches. They help maintain focus on what matters most.
This balance of support and challenge is what drives progress.
“My mentor knew when I needed reassurance, but also when to push me. That balance made a huge difference to my confidence.”
Why it matters
The quality of mentoring can shape a trainee’s experience in very real ways.
It can make the difference between feeling isolated and feeling supported. Between uncertainty and growing confidence. Between simply coping and genuinely developing.
It also reinforces an important message about the profession itself.
Teaching is not something you do alone. It is collaborative. It is reflective. It is something you continue to learn and refine over time.
At Portsmouth SCITT, we work closely with our partnership school to ensure that mentoring is consistent, purposeful and rooted in the training programme. Mentors are not just experienced teachers, but key partners in developing the next generation of teachers.
Final thoughts
There will always be moments during teacher training that feel challenging.
A good mentor does not remove those moments, but they help you navigate them.
They help you keep perspective, focus on what matters, and recognise how far you have come.
And often, they are the person who helps you start to see yourself not just as a trainee, but as a teacher.
