He is going to be promoted since he is a notch above others.
他即将晋升，因为他较别人略胜一筹。
be a notch above someone直译过来就是：“在别人上面一个等级”，这个短语的正确意思是：“比别人略胜一筹”。因此，当美国人说"He is going to be promoted since he is a notch above others."时，他/她要表达的意思就是:"His promotion is due to his better performance."、"He will be promoted because he is better than others at work."。
