Application submissions require the Supplemental Questionnaire to be completed.

Responses to supplemental questions will be scored using position-specific criteria. Please provide specific and detailed responses of a reasonable length to allow for a thorough assessment of your qualifications. Responses that state, "See Resume" or "See Application" may be considered insufficient and therefore may not be scored.

The selection procedure will consist of the following examination:

An Application and Supplemental Questionnaire Appraisal Examination (weight 100%) will be conducted to evaluate each applicant's application and supplemental questionnaire for satisfaction of minimum qualifications (pass/not pass); and for educational coursework, training, experience, knowledge, and abilities which relate to this position. Personally identifiable information (PII) is removed from the standard application fields and applicable attachments. This PII blind screening practice redacts a candidate’s personal information that could potentially influence or bias the scoring process. Personal information includes the applicant’s name, former last name, address, phone number, email, driver's license number, school name, education start and end dates, age, date of birth, gender, and race. This PII blind screening practice helps contribute to a fair and equitable examination process.

Each applicant will be evaluated based on the following criteria:

• Relevance of work history, related experience, and achieved level of education and/or training as described in the application and responses to the supplemental questions.

Candidates demonstrating possession of the minimum qualifications will be placed on an employment list in order of most qualified to least qualified based on the achieved score received in the Application and Supplemental Questionnaire Appraisal Examination which evaluates the education, training, experience, skills, knowledge, abilities, and other qualifications that you demonstrate in your application and/or response to the supplemental questionnaire. Please be aware that resumes and cover letters are not typically evaluated in the Application and Supplemental Questionnaire Appraisal Examination. Scores may be adjusted based on such factors as the number of candidates, anticipated vacancies, past practice, and natural breaks in the scores achieved by this group of candidates.

Additional Information

A background investigation may be required prior to employment. Candidates referred to departments for a selection interview are typically required to sign authorization and release forms enabling such an investigation. Failure to sign prescribed forms will result in the candidate not being considered further for that vacancy. Reference information will not be made available to candidates.
