Conn. Gen. Stat. § 5-227b

(b) If the commissioner has granted a waiver of examination in accordance with subsection (a) of this section, the commissioner may delegate to a department head the authority to recruit for such position pursuant to a delegation plan, except no delegation plan shall be required for such delegation in the case of a waiver of examination granted pursuant to subdivision (1) of subsection (a) of this section. For waivers of examination granted pursuant to subdivisions (2) to (4), inclusive, of subsection (a) of this section, the department head shall submit a delegation plan to the commissioner, and the commissioner may grant a full or partial delegation to the department head. The department head shall obtain the commissioner's approval of the delegation plan prior to undertaking any recruitment efforts. Any such delegation plan shall (1) include standards for the posting of positions with a minimum time period of not less than one week; (2) specify the manner in which such notice shall be posted; and (3) specify the procedures for accepting and rejecting applicants based upon the minimum required qualifications. Where the department head has identified a candidate suitable for appointment and prior to making a formal or informal offer of employment, such department head shall submit the application, any supporting documentation for such candidate and the applications of such additional candidates such department head deems eligible for appointment to the commissioner for certification that such preferred candidate has met the minimum qualifications of experience and training as set forth in the job specification. Once written certification is granted, the department head may make an offer of employment to the candidate certified by the commissioner.

(c) Any recruitments performed by a department head pursuant to this section may be subject to post audit by the commissioner.
