This is the entry, developmental and first (Specialist) working level in the series. While in a trainee capacity, incumbents work under close supervision and learn to perform a variety of technical and analytical business service activities. As their skills and abilities develop, incumbents are expected to perform with increasing independence. Fully trained incumbents may, under supervision, independently perform technical business service work of a routine nature in a variety of functions; assist in the performance of more difficult and complex technical and analytical business service work; or be assigned responsibility for one or more of the least complex business service functions which are Equipment and Supplies Management, Support Services and Building Maintenance. (Analytical business service work performed at this level is described as that which would otherwise be appropriate for a Management Services Technician.) Positions at this level are nonsupervisory but may serve as lead over lower level clerical and other staff. Positions are permanently allocated to this class when the major portion of the duties does not include independent responsibility for the more difficult and complex assignments found at the Business Service Officer I (Specialist) level.
