The Comprehensive Ranking System or CRS points calculator is a system adopted by the Canadian Government for evaluation, allocation of scores, and offering ranks. It is for the profiles of the candidates in the pool of Federal Express Entry. Your score under the CRS calculator will be determined by the answers that you have offered in your profile in Express Entry. The overall score that you get under CRS will decide if you are qualified for receiving Permanent Resident status. So this is a tool that decided your eligibility for immigrating to Canada. The point calculator under CRS has been modified for assessing the scores of the candidates under the skilled worker immigration category. Applicants are now required to secure at least 67 points to qualify for submitting an application for skilled worker immigration. The assessment is based on diverse factors like age, work experience, language proficiency, education, etc.
