Gain valuable insight into the decision-making skills of your entering surgery residents.
“ACS ERRA allows for high-level judgment assessment that then enables the program, the program director, and the intern (general surgery or those destined to end up in a surgical specialty) to work together to enhance autonomy, purposeful indirect supervision, and keep our patients safe."
The Entering Resident Readiness Assessment (ERRA), developed by the ACS Division of Education, is an innovative online, case-based instrument to measure the preparedness of entering surgical residents (PGY-1).
ACS ERRA focuses on clinical decision-making for cases frequently encountered at the beginning of resident training. The assessment provides surgery program directors and residents with psychometrically rigorous measures of key decision-making skills needed to safely assume their new clinical responsibilities.
Short case scenarios are used to address essential clinical topics through special "key features" questions that specifically assess clinical decision-making skills instead of simple recall of factual knowledge. Results of the assessment can be used to identify strengths and to develop learning plans in areas that may need reinforcement for individual residents or the entering group as a whole.
The ACS ERRA is a psychometrically rigorous, formative assessment of PGY-1 preparedness, focusing on 20 clinical topics that incoming surgical residents are likely to encounter. The ACS Division of Education methodically defined a validated domain of cases and recruited expert faculty to develop the assessment. Residents respond to 40 short clinical cases, each followed by questions that specifically assess key clinical decisions. As a formative tool, the ACS ERRA is intended to assess residents' decision-making at the time they enter surgical residency; it is not intended to measure factual knowledge recall or to be used as a summative assessment.
Response formats include short, write-in answers (for example, listing possible diagnoses) or the selection of options from menus containing possible next steps in the investigation or management of the problem. The specially designed questions use the internationally proven “key features” approach as established by Georges Bordage, MD, MSc, PhD, and Gordon Page, MA, EdD, in which the case scenarios require medical knowledge to be applied appropriately at critical decision points during management of the case. Key features may include essential steps required to resolve a problem, a particularly challenging aspect in the identification and management of the problem, or actions most likely associated with errors in practice. Because not all steps in the management of patient problems are equally important, assessment time is best spent by focusing exclusively on the most challenging aspects that will distinguish appropriate performance.
The ACS ERRA is a proctored assessment, requiring a staff member to monitor the room where residents take the assessment. The administration is allowed at any time within the Administration Window, indicated above. Each resident will need their own computer with strong Internet connectivity. Ideally, residents will take the assessment in the same window, however, it is possible to split administration. Contact the ACS ERRA staff for more information.
Residents are allowed up to three hours to complete the assessment; however, the average is closer to a two-hour duration. Results will be provided by late July.
ACS staff will be happy to provide training and assistance with the technical and administrative details of the assessment.
Following the assessment, program directors and residents are provided with psychometrically sound, nationally benchmarked, individualized score reports for each resident. The reports identify specific areas of strength, weaknesses that need to be addressed, areas with potentially harmful actions, and corresponding suggested resources for additional study. Designed for formative purposes, the ACS ERRA score reports outline steps for residents to identify areas for improvement, develop a personalized learning plan with the accompanying template, and meet with their program director to put their plans to action over the subsequent months.
Following the assessment, program directors will receive confidential reports each providing data on the preparedness of residents in each clinical topic. Data are provided on reports for each individual resident and for the program at-large, and include aggregate national data for comparison with other participating programs nationwide.
Individual resident reports include information regarding individual scores. These reports will allow program directors and each resident to recognize specific areas of strength and to develop learning plans to address focused areas for increasing preparedness.
Program reports list the topic areas and resident levels of performance based on the percent answered correctly in each area, as well as the overall distribution of scores on the assessment. Results can help inform curricular changes for the cohort.
An Individual Learning Plan (ILP) template is included with each individual score report. The template is designed to facilitate conversations between the program director and resident to help define focused learning goals and to identify specific actions for residents to take.
The ACS Division of Education methodically defined a validated domain of cases and recruited expert faculty to develop the assessment. Four pilot studies were conducted in a step-wise sequence with improvements made after each pilot. The first pilot was a small study that focused on the test takers’ understanding of the clinical cases. The second pilot study asked users to provide feedback on the assessment’s online presentation and functionality. The technical feasibility study tested the technical operations and capacity of the online server. Most importantly, the psychometric pilot study was conducted during the summer of 2017 across 18 surgical residency programs nationwide: the results demonstrated validity and psychometric rigor.

Development is ongoing to protect the integrity and quality of the assessment.
