For some, it will be their first day ever, whether they're starting primary or making the leap to high school.
We've been asking Leader readers from across Wrexham and Flintshire to share photos of their youngsters as they set off for their first day.
From first day or school or back to school, proud parents and grandparents have been sharing their photos.
There are still more schools to welcome back their staff and students later this week, so keep sharing your photos.
Whether your little ones or big kids have started or returned to the classroom, you can still get in touch.
Maybe you're a new teacher or one with more experience under your belt, we would love to see your smiling faces too.
You can use the link at the end of this article to share your photos, or you can email your details to claire.pierce@newsquest.co.uk
