krok

Krok is a term found in several Slavic languages, most commonly meaning a unit of movement such as a step or pace. In Polish, krok denotes a step, while in Ukrainian and Belarusian, the related form крок (krok) carries the same sense. The word derives from Proto-Slavic roots meaning “step” and appears in everyday expressions such as step-by-step phrases. In many contexts, krok functions as a generic measure of progression or sequence, used both literally and figuratively.

In Ukraine, KROK also designates a notable system of national licensure examinations for medical graduates. The KROK examinations are typically organized in multiple stages and are taken to demonstrate readiness for professional practice or further training. Commonly referred to as KROK-1, KROK-2, and KROK-3, they are intended to assess knowledge across preclinical, clinical, and practical domains, respectively. The exams are generally administered by national medical authorities and are a prerequisite for the right to practice medicine or enter residency programs. Formats have increasingly integrated computer-based testing and standardized question formats, with later stages incorporating elements that evaluate clinical decision-making and patient care. The KROK series is widely recognized within Ukrainian medical education as a key component of the licensing pathway.

Overall, krok serves as both a basic linguistic concept related to movement and a formal credentialing framework in Ukrainian medical education, reflecting the word’s broad semantic reach.
