The Canadian government uses the CRS to score and rank Express Entry candidates.
Anyone who is considering immigrating to Canada under an Express Entry program will very quickly encounter the Comprehensive Ranking System (CRS). Canada started using the CRS when it introduced Express Entry in 2015. The CRS is a detailed and evidence-based approach designed to identify immigrants who have the best chance of succeeding in the Canadian labour market. It does this by awarding Express Entry candidates points based on core human capital criteria such as age, education, language skills, and work experience. Candidates are then ranked against each other based on their CRS score.
