The Internal Medicine In-Training Exam (ITE) is an annual assessment administered by the American College of Physicians (ACP) to internal medicine residents across all three years of training. If you're an IM resident, you'll take it every year of residency—and how you approach it matters more than most residents initially realize. This guide covers what the ITE exam for internal medicine tests, how it's scored, what your score actually means, and how to use ITE performance data to drive your board preparation.
The ITE isn't just a checkbox on your annual residency schedule. It's one of the best predictors of ABIM Board Certification exam performance, and programs use ITE data to identify residents who may need additional support before boards. Taking it seriously each year—especially in PGY-2 and PGY-3—pays dividends when it's time for your actual boards.
The ITE consists of 240 multiple-choice questions administered over a single day (typically in October). The exam runs in two 120-question blocks with a lunch break in between. Questions are single best answer format—four options, one correct. There's no penalty for guessing.
Each question is a clinical vignette: you're given a patient scenario (age, presentation, relevant history, exam findings, labs) and asked to select the best next step, most likely diagnosis, most appropriate treatment, or expected finding. The question style mirrors the ABIM Board Certification exam almost exactly, which is intentional—the ITE is built by ACP as a formative practice exam for the boards.
The ITE covers the full breadth of internal medicine. Content is weighted roughly according to disease prevalence and clinical importance in internal medicine practice:
ITE scores are reported as a percent correct and a percentile rank compared to residents at the same PGY level nationally. Your percentile rank is the number most programs focus on—it places your performance in the context of all IM residents taking the exam in the same year of training.
Score reports are provided to both the resident and the program director. You'll see your overall performance and a breakdown by content area—which lets you identify the specific domains where your knowledge is strongest and weakest. Program directors use this data in both aggregate (to assess program curriculum) and individually (to provide targeted support to residents at risk).
What's a good ITE score? As a benchmark:
These aren't absolute thresholds—many residents below the 35th percentile on ITE pass boards, and the ABIM exam has its own character. But the correlation between ITE performance and ABIM outcomes is well-documented in the literature, which is why programs take low ITE scores seriously.
Research published in the Journal of General Internal Medicine and other journals consistently shows that ITE percentile rank in PGY-3 is the strongest single predictor of first-attempt ABIM Board Certification exam success. The relationship isn't perfect—exam-day performance, targeted board review, and individual variation all matter—but the correlation is strong enough that a low PGY-3 ITE score should prompt immediate, serious board preparation.
Programs that use ITE data most effectively:
Because the ITE mirrors the ABIM boards so closely, the optimal strategy is the same for both: high-quality question bank practice combined with systematic content review.
The single most effective preparation tool for the ITE—and for boards—is a high-yield question bank. UWorld Internal Medicine is the gold standard. Amboss is a strong alternative. Use your question bank in timed, tutor mode: read the explanation for every question, even the ones you get right, because the explanation often includes adjacent knowledge that fills gaps. Aim to complete at least 1,000–1,500 questions between ITE administrations in PGY-2 and PGY-3.
During residency, your reading should be driven by the patients you see. Every interesting case is an opportunity to read deeply on a topic—pathophysiology, management guidelines, relevant clinical trials. This kind of case-based reading builds the durable understanding that question banks reinforce. UpToDate, ACP's MKSAP (Medical Knowledge Self-Assessment Program), and Harrison's are the standard references.
ACP's MKSAP is the official companion resource to the ITE. It covers all ITE content areas at the depth the exam tests, and questions are written in the same style. Many programs provide MKSAP to residents; if yours does, use it. Working through MKSAP questions in the content areas where your ITE performance was weakest is one of the highest-yield ways to improve your next ITE score.
Use domain-specific practice tests to benchmark where you stand before the ITE. The ITE Cardiovascular Disease and ITE Pulmonary and Critical Care practice sets let you drill specific content areas and identify which subtopics within each domain you need to review.
When you get your ITE score report, the most productive thing you can do with it is use the content area breakdown to build your next year's study plan. Don't just look at your overall percentile—look at where you performed furthest below your overall level. If your gastroenterology section was 15 percentile points below your total, that's where you spend the next few months of targeted reading.
Year-over-year ITE improvement is meaningful. Residents who systematically identify weaknesses from each ITE and address them with targeted study consistently improve their scores across PGY years. The ones who don't use ITE data tend to plateau—because they keep studying what they already know rather than addressing gaps.
The ITE also serves as a pacing check for boards preparation. A PGY-2 resident with a below-average ITE score isn't in crisis—there's still a full year of training ahead. A PGY-3 resident with the same score has a more pressing timeline. Use the ITE to calibrate how much of your remaining training time needs to be directed toward systematic board preparation vs. the normal rhythms of clinical learning.
For content area practice, the ITE Gastroenterology and Hepatology and ITE Endocrinology practice sets give you domain-specific question practice that mirrors the ITE format. Work through them honestly—timed, without looking things up—to get an accurate picture of where you actually stand in each content area.
