Jit Sin High School used to share the same compound with Jit Sin Independent High School at Aston Road. In 1992, Jit Sin High School moved to a purpose-built campus in Taman Sri Rambai. Students attend classes from Form 1 to Form 6, they used to organise into morning and afternoon sessions. But now, all forms have changed to morning session since the start of the year 2020. Jit Sin High shares the same school anthem with Jit Sin Independent High School as well as its primary school counterparts, SJK Jit Sin & SJK Jit Sin. The school is known nationwide as a top elite school for its excellent academic results in public examinations such as Penilaian Menengah Rendah, Sijil Pelajaran Malaysia and Sijil Tinggi Persekolahan Malaysia consistently every year. The school's success is largely attributed to its merit-based admission of students from primary vernacular education. The entry requirement is set at a maximum of 9 accumulative points scored in the Ujian Pencapaian Sekolah Rendah over 8 subjects, where an A constitutes to 1 point and E is 5 points, meaning that prospective students had to score straight As, or near-straight As, whomever ranked best, so as such until the intake for that particular academic year is full. In October 2011, Jit Sin High School was awarded the title of Cluster School of Excellence, and is the first vernacular secondary school in Penang to achieve this premier status.
Structure
The school consists of two sub-schools, divided by form level. The sub-schools are:
Secondary school: Form 1 to Form 5
Pre-University: Form 6
A new building due north to the original building is opened on 22 June 2019 for Form 5 and Form 6 students. The new building consists of 6 floors with 2 main elevators and 2 smaller elevators.
Jit Sin High School branch campus
New branch campus at Jalan Tasek, Simpang Ampat, Penang, located at the south of Bukit Mertajam is currently undergoing construction. It is built due to capacity constraints at the main campus, and to cater to an ever-expanding student intake.
In 2007, the Harmonica and Choir Club and Environmental Cadets have been disbanded as a uniform body and re-categorised into clubs, following new guidelines set by the Ministry of Education. The school has seen changes made by the 5th and current principal in order to improve the schooling atmostphere as well as the declining discipline among the students – notably the installation of closed-circuit television surveillance cameras. Stricter regulations has also been enforced by the school disciplinary board. Wi-Fi is available campus-wide by the IT Department in 2010, but made exclusive to the staff room.
