1 ORPAT VALIDATION STUDY FOR CORRECTIONS OFFICER Authored By: Rick Gardner Senior Research Analyst Date: 2006

2 ORPAT VALIDATION Introduction The Oregon Physical Abilities Test (ORPAT) was originally developed for use in assessing police officer fitness and agility capabilities. Its use in other law enforcement disciplines requires additional validation. Content Validity For the ORPAT test to be valid for law enforcement disciplines other than police, it is necessary to validate the test against known physical requirements of the specific job under consideration. There must be a reasonable correlation between the skills and abilities ORPAT assesses and the demonstrated critical and essential physical tasks entry-level corrections incumbents perform in on-the-job (and in training), after completing the academy training program. The primary basis for determining content validity is the Job Task Analysis (JTA). In 2006 a comprehensive physical task JTA was completed for entry-level corrections officers. From this assessment an updated list of essential physical tasks and requirements for the job of corrections officer was established. Because the ORPAT is a hybrid testing process, it combines elements of both classical job sample testing and physical abilities testing. Determining content validity, therefore, is a two-part process. The first step is to reconcile actual physical activities performed in the ORPAT (stations) with the validated corrections officer physical job requirements; the second is to validate overall constructs (what ORPAT assesses as a whole, in addition to the individual stations) against known, validated job requirements). Validation Levels Currently, ORPAT is used in the corrections curriculum without a minimum pass cut-off score. Students must take and complete a pre and post test and show some degree of improvement between the two. This is the only requirement. As such, it is NOT used as testing or employment screen, other than students must be in sufficient physical condition to successfully complete the course. ORPAT is currently used in a manner that does NOT significantly impact the correction students employment. However, both ORPAT and Defensive Tactics (DT s) present risk for personal injury in mandatory training, which in tern represents a potential risk to employment. Page 2

3 ORPAT VALIDATION FOR CORRECTIONS OFFICER Therefore, it is important to establish a clear, logical and reasonable link between these training activities and the bona fide job performance requirements of being a corrections officer. Because ORPAT does not constitute an actual functional employment test for corrections officers, its validity is subject to less stringent requirements. It s present use in the corrections curriculum is primarily diagnostic and for self-awareness, so recruits have a clear understanding of their personal job-related physical abilities. It also serves to motivate recruits to participate in Physical Training (PT s) and direct more effort towards personal physical health and conditioning. In order to be valid for this application, the use of the ORPAT (in total) must be reasonably representative of the physical requirements of being a corrections officer. It is not strictly necessary that each station in the ORPAT correspond to a defined critical and essential task, so long as the overall assessment process can be demonstrated to be reasonably job-related. In this study, both the specific stations of the ORPAT and its overall functioning are examined and compared against the 2006 Corrections Physical Task JTA findings. The first portion of this analysis focuses on the specific ORPAT stations, beginning on page four (4). A complete list of validated critical and essential physical tasks is provided. For each station, the applicable items are noted under the description of the station. In addition, for each station the validity level for that specific station is noted. This is determined by the degree to which the specific station can be related to one or more of the critical and essential tasks. Validity ratings run from excellent to poor.

20 ORPAT VALIDATION CONCLUSIONS While two of the specific stations in the ORPAT do not correspond to specific critical and essential tasks identified in the 2006 Corrections Officer JTA (Five-foot jump, 18 Barrier Jump), and one (Crawling) does so marginally, unlike pure physical abilities tests, such as the Coopers, these stations do correspond to tasks that are performed by corrections officers, albeit at a somewhat lesser frequency and/or criticality level than that required to meet the mathematical cutoff for critical and essential. Jumping (overall average of Consequences of Inadequate Performance = 2.5 out of 6, over 60% of survey respondents indicating they perform these tasks once or more per year)* Crawling (overall average of Consequences of Inadequate Performance = 2.7 out of 6, over 60% of survey respondents indicating they perform these tasks once or more per year.)* * Source DPSST 2006 Corrections Officer Physical Task Job Task Analysis The overall abilities assessed by the ORPAT correlate very well to the critical and essential tasks of being a corrections officer, with all but Speed addressing multiple critical and essential tasks. If the ORPAT were to be used as a graded test, or in employment screening, some modifications in individual stations might be desirable. However, in its current application there is sufficient evidence to assert that ORPAT is a defensible assessment tool for the physical conditioning and functional abilities of corrections officers, and reasonably approximates the established physical demands of the job. This assertion is strengthened by five years of measurements showing that if the ORPAT score of mean plus one standard deviation (6:30) were used as a standard, not only is there no disparate impact for females and minorities, there is actually relatively little difference in the pass rates of female, male and minorities. The test is clearly non-discriminatory at the first standard deviation. As is, the ORPAT constitutes a defensible and reasonable assessment tool for examining the overall job-related fitness and physical functioning of corrections officer candidates.
