Note to Applicants: It is essential that you complete all sections of your application and supplemental questionnaire thoroughly and accurately to demonstrate your qualifications. A resume and/or other related documents may be attached to supplement the information in your application and supplemental questionnaire; however, it/they may not be submitted in lieu of the application.
SUPPLEMENTAL QUESTIONNAIRE - qualifying: All applicants are required to complete and submit the questionnaire for this examination AT THE TIME OF FILING. The supplemental questionnaire may be used throughout the examination process to assist in determining each applicant's qualifications and acceptability for the position. Failure to complete and submit the questionnaire may result in removal of the application from further consideration.
APPLICATION EVALUATION - qualifying: All applications will be reviewed to determine whether or not the stated requirements are met. Those individuals meeting the stated requirements will be invited to continue to the next step in the screening and selection process.
TRAINING & EXPERIENCE EVALUATION: A Training and Experience Evaluation (T&E) is a structured evaluation of the job application materials submitted by a candidate, including the written responses to the supplemental questionnaire. The T&E is NOT a determination of whether the candidate meets the stated requirements; rather, the T&E is one method for determining who are the better qualified among those who have shown that they meet the stated requirements. In a T&E, applications are either scored or rank ordered according to criteria that most closely meet the business needs of the department. Candidates are typically scored/ranked in relation to one another; consequently, when the pool of candidates is exceptionally strong, many qualified candidates may receive a score or rank which is moderate or even low resulting in them not being advanced in the process.
The eligible list established will be created from the scores resulting from a Training and Experience Evaluation (T&E). In a typical T&E, your training and experience are evaluated in relation to the background, experience and factors identified for successful job performance during a job analysis. For this reason, it is recommended that your application materials clearly show your relevant background and specialized knowledge, skills, and abilities. It is also highly recommended that the supplemental questions within the application are completed with care and diligence. Responses such as "See Resume" or "Refer to Resume" are not acceptable and may disqualify an applicant from further evaluation. Applicants must earn a score of seventy percent (70%) or higher to qualify for placement on the eligible list.
If there are three (3) or fewer qualified applicants, a T&E will not be conducted. Instead, a score of seventy percent (70%) will be assigned to each application, and each applicant will be placed on the eligible list.
Candidates successfully completing the examination process may be placed on an eligible list for up to a period of one (1) year. The eligible list established from this recruitment may be used to fill current and future Regular (including Temporary, Fixed-Term), Intermittent, and Extra Help this and similar vacancies within the Resource Management Agency. There is currently one (1) Regular vacancy within the Code Compliance Division, Weights & Measures Section.
