Assessment index of current track and field technical course
| Technical courses 50% of the exam | Theory course examination 30% | Usual score 20% |
|---|---|---|
| Technical course assessment content: shot-put, high jump, hurdles, etc. pass line 60 points | Technical principle of running jump shot, track and field judging method and field specification, theory examination pass line 60 points | Usually the result is mainly for the attendance record, and the teacher’s subjectivity is strong |
