This research focused on the current status of senior high school mathematics teachers’ tutoring in extra-curricular time and adopted face-to-face interview way to collect data. A total of 34 mathematics teachers from 6 senior high schools in Shandong Province participated in this investigation. The results indicated: (1) 96.67% of teachers usually tutored outstanding students; (2) 93.33% of teachers always adopted the one-to-one form to tutor; (3) 89.33% of teachers tutored students in free class ; (4)89.02% of teachers tutored students not more than 10 minutes; (5) 90.21% of teachers generally tutored students knowledge about problem solving, etc. So the current ways of senior high school mathematics teachers’ tutoring was obviously too simple and superficial. This should be the direct reason resulted in the poor effect of mathematics tutoring in extra-curricular time in current senior high school.
