CSA meaning in Medical ?

Step 2 Clinical Skills (Step 2 CS) of the United States Medical Licensing Examination (USMLE) was an exam administered to medical students/graduates who wish to become licensed physicians in the U.S. It is similar to the COMLEX-USA Level 2-PE exam, taken by osteopathic medical students/graduates who seek licensure as physicians in the U.S. For US medical students, the exam fee is $1,300 (as of 2020). For medical students at non-US medical schools, the tests cost is higher—currently $1,535. These fees do not include costs associated with travel and lodging to take the test. Historically, US students have taken Step 2 CS late in their senior year, prior to graduation. However, now that more residency programs require students to record a passing score, many US medical schools recommend students take Step 2 CS in the fall of their senior year.

On May 26, 2020, in response to the COVID-19 pandemic, the USMLE "suspended Step 2 CS test administrations for the next 12-18 months."

On January 26, 2021, the USMLE announced that the work to relaunch a modified form USMLE Step 2 CS had been discontinued citing rapidly evolving medical education and changes in other standardized exams, like computer-based simulations in Step 3, that would supplement medical students' education in place of Step 2 CS.
