Mobile phone policy

A clear mobile phone policy is a really important part of modern schooling. This school has provided us with their policy.

Mobile phone policy

Provided by the school and not part of our review

To remove the distraction and disruption of mobile phones from the school environment – and to provide pupils with a period of six hours each day where they can focus on learning, socialising and communicating – we have introduced a partnership with Yondr. Each pupil has their own Yondr pouch. Every morning pupils put their phones into their pouch and lock it as they enter the school site. At a designated time before the end of the school day, unlocking bases are activated and as pupils leave the school site they are able to unlock their pouches and use their phones.

What is this?

Facilitating A levels are ones that are commonly needed for entry to leading universities. They are: biology, chemistry, physics, mathematics, further mathematics, geography, history, English literature and classical or modern languages. The % of pupils achieving AAB or higher may therefore decrease if many pupils have opted not to take two or more of the facilitating subjects mentioned.

SEN overview

Sydenham High School is a mainstream school. The school may provide support for students with special educational needs as detailed below. If you require more information on conditions the school can support, we encourage you to contact the school directly.

SEN statement

Provided by the school and not part of our review

The school's special needs policy follows the recommendations of the Code of Practice (2001). At admission each pupil is looked at as an individual case to see whether the school can effectively meet her needs. A girl would only be refused entry if she was unable to attain the required academic standard or if the school was unable to cope with the child's difficulty once every effort had been made to accommodate her needs. The school has a Learning Support Department run by a qualified dyslexia teacher. Individual difficulties (eg mild dyslexia, dyspraxia, ADHD, Aspergers) are handled as appropriate by the Learning Support Department. Pupils whose difficulties form a significant barrier to learning may have an Individual Education Plan and some targeted help from the Learning Support Department. Pupils with specific learning difficulties should be able to cope in mainstream classes but the school offers a supportive environment in which staff are made aware of the ways in which these students can be supported within the classroom. The Junior Department also has access to well qualified perpatetic special needs teachers who can give long term individual support during school time and parents may wish to use this facility for which an extra charge is made.
