How can I tell when a particular test will be given by Mount Vernon Civil Service Commission?

CMV Civil Service

Not all examinations are held on an annual basis. Examinations are prepared and scheduled by the New York State Civil Service Commission. Civil Service requests examinations to be scheduled based on the number of positions, the length of the current eligible list, the age of the list, and the turnover of employees within the title. Eligible lists are valid for a minimum period of one year from the date of establishment and up to four years at the discretion of the Commissioner of Civil Service.

In order to find out if a specific examination is being offered, you must check on the schedule of announced examinations.
