Albury High School plans to introduce lockable pouches next year that students put their phones in at the start of the day, keep with them, and then attend a station to unlock them when leaving school.

Principal Darryl Ward said the system was used successfully in other NSW schools and likened it to security clips on clothing in stores.

"We'll put plenty of stations out so kids can exit the school smoothly," he said.

"Phones have always been misused by people - adults and children - inappropriate texts, inappropriate comments, bullying, harassment, I just think enough's enough, really.

"I just think we want to create a really positive environment in the school and have some time off from those comments on social media."

Mr Ward said the scheme also aimed to protect learning time, reducing interruptions during classes.

Teachers will be able to unlock the pouches if students need phones for a subject, such as photographic and digital media.

A NSW policy introduced this year allows secondary school principals to restrict or permit students' mobile phone use, in consultation with the school community.

Mr Ward outlined the new plan fully in the school newsletter and invited feedback.

He said the initial response had been "overwhelming support for our position".

The Parents and Citizens Association, Student Representative Council and prefects have been consulted, with several logistical points still to be finalised.

"Our basic policy will be no pouch, no phone at school," Mr Ward wrote in the newsletter.
