What This Site Is
The CRC Toolkit exists because the clinical research coordination profession is underserved by free, high-quality, regulation-grounded resources. The calculators handle the specific compliance math that CRCs perform repeatedly — IP accountability percentages, visit window deadlines, creatinine clearance for eligibility calculations, date arithmetic for reporting deadlines. The articles cover the regulatory framework in the depth that working CRCs and certification candidates need: not summaries, but full explanations grounded in the actual regulatory text.
The site is editorially independent. Content decisions are based on what is useful and accurate. Some pages include Amazon affiliate links for products commonly used in clinical research settings, this is disclosed on every page where affiliate links appear and in our Privacy & Disclosures page.
