Bradbury Junior School caters for students aged 5 to 11 years and is under the administration of the English School Foundation. Situated above Happy Valley, the school is made up of over 50 nationalities and 720 students of various backgrounds.

The school's curriculum is based on the British National Curriculum, but modified to fit the context of Hong Kong. Efforts have also been made to put the ESF Entitlement Curriculum - 'In Pursuit of Excellence' - into practice, which requires that certain areas of the national curriculum are taught to students, such as the core subjects of English, mathematics and science.
