Usually the dates are declared only 2–4 months prior to the examination. After the declaration, only about one month is usually given to submit the application form.
The IBR department of every state usually functions under the Department of Labour of that state and a separate page is often assigned on the Labour Department website for the concerned state.
Very few departments update their sites regularly. Therefore, to know the examination-related information for a particular state, one has to directly contact the respective Boiler Department.
