Principal Psychometrician Resume Example

CAREER SUMMARY: I have over 25 years of assessment experience and have an in-depth understanding of how assessments are constructed, validated, and implemented for learner outcomes, personnel selection, learning and development, including an area of expertise on related psychometric topics, such as clinician-mediated assessments (e.g., ClinRO, ObsRO). As principal psychometrician since 2011, I have built a new clinician-rated assessment for use in hospitals and simulation labs. I have been using validity research studies to collect empirical evidence in support of the reliability of measures and validity of participant's measure interpretation in terms of content validity, optimum scoring structure, unidimensionality, reliability, invariance, responsiveness, consequential, and interpretability. Two additional area of expertise are: (1) Rating Scale Analysis - empirically test that the rating scale responses behave in a manner consistent with the intentions of the developers; and (2) Dimensionality Analysis - empirically determine the unidimensionality of the ClinRO. Unidimensionality results in additivity, implying the ClinRO variables (e.g., clinicians, evaluation criteria, participants) can be expressed as real numbers on a common interval scale. In contrast, a self-report assessments (e.g., PRO/ePRO) does not lend itself to reliability estimate calculations because raw scores are not linear, are potentially misleading, and do not support valid mathematical operations. (The ISPOR website would not allow me to investigate this matter.) My role requires that I keep abreast of standards, best practices, and the latest developments in assessment technology and innovation including the use of computer adaptive tests, and the design and implementation of innovative performance assessments. Finally, I serve as an internal expert and consultant to clients on assessment related issues.

Enthusiastic individual with superior skills in working in both team-based and independent capacities. Bringing strong work ethic and excellent organizational skills to any setting. Excited to begin new challenge with successful team.

• BOARD OF EDUCATION OF THE CITY OF NEW YORK Brooklyn, NY Bureau Director 6/94 - 12/02.
• Directed staff and test development activities which ranged from: identifying test development needs, developing timelines, scheduling meetings, contacting and contracting with consultants and subject matter experts, and conducting training sessions on rating, content validation, item writing and sensitivity reviews; administering job analyses survey, and analyzing survey, field test, and test results.
• All activities had to be completed within budget.
• Maintained job analyses database on 132 pedagogical and supervisory licenses.
• Based on empirical evidence, job analyses surveys were distributed every two years to ensure job related tasks were appropriatelyreflected on the licensure examination test blueprints.
• Complied with the Uniform Guidelines on Employee Selection Procedures (Equal Employment Opportunity Commission, Civil Service Commission, U.S.
