The Peninsula School is working with the Department of Education and Early Childhood Development to allocate a Victorian Student Number (VSN) to each student at the School.

The VSN is a student identification number that is being assigned to all students in government and non-government schools, and students in Vocational Education and Training Institutions. The number, which is unique to each student, will be used as a key identifier on a student's school records, and will remain with the student throughout his or her education, until reaching the age of 25. The VSN is nine digits long, randomly assigned, and tied to information about the student (name, gender, date of birth).

The introduction of the Victorian Student Number will provide the capability to accurately detect patterns of student movement through, and departure from, the Victorian education and training system. It will greatly improve the collection and analysis of timely and accurate data about education in Victoria. The Department collects information to track improvements made to the education system, identify areas that require further improvement, and to analyse trends and identify future needs. The VSN will improve the accuracy, reliability and completeness of this information, providing a better basis for assessing needs and developing policies to meet them.
