出勤率（chū qín lǜ）是汉语词语，意思是指实际出勤数与应该出勤数的比率。例如一个班有50个人，当天有45个人来，出勤率就是90%；50个人都来了，就是100%。
Attendance rate (chū qín lǜ) is a Chinese term, which means the ratio of actual attendance to expected attendance. For example, if there are 50 people in a class and 45 of them come on the day, the attendance rate is 90%; if all 50 people come, it is 100%.
