To defer KASNEB examination, you need to write a formal application letter to KASNEB explaining why you want to defer. You must provide evidence to justify reasons for deferment. For instance attach medical form, transfer of work station letter, etc.
You must submit your deferment letter 30 days before start of exams unless it is an emergency case like sickness.
Deferment letter and supporting evidence attachment can be dropped in any Huduma Centre KASNEB Desk.
