The Punjab School Education Board (PSEB) Senior Secondary examination is the Class 12 board examination for students in Punjab, conducted by a body that "came into existence through a legislative enactment in November 1969 for the development and promotion of school education in the state of Punjab." Biology is one of the science subjects in the Senior Secondary programme. Candidates typically reach it after Class 11 study in an affiliated or associated school, and the subject is assessed through a written board theory paper and a practical examination with an external examiner, since the Board publishes both "Practical Instructions for Centre Controllers" and a "Letter for External Examiner for Practical paper." The Board publishes the syllabus, textbooks (e-Books), a question bank, the "Structure of Question Paper" and "Model Test Paper/Sample Of Question Papers," so candidates can see the paper design and the style of questions before the exam. The most recent announced Senior Secondary session is February/March 2027, for which the Board has issued examination form schedules, fees and instructions, along with a separate schedule for Re-appear/Compartment, Additional Subject and Division Improvement candidates.
