麻烦帮忙解释一下一些名词的中文名称好不好？
如下：
Subject Mastery
Core Competency
Teaching Competency Model．
如果可以的话，希望能帮忙翻译一下下面这些话，觉得好的，会提高分值。
The competencies has been grouped into broad clusters. As competencies are not isolated characteristics,it is insufficient to demonstrate just one Competency to a high level. On the other hand,leaders need not exhibit all the competencies to attain success. Rather,leaders need to have a balance of competencies across clusters,and a combination of competencies within each cluster.
Cluster Title: Competency Title
Definition: explains the overall behaviour in action.
Core Question: Focuses attention on the underlying theme of,or value added by the Competency.
Why It Matters: Explains the significance of the Competency in delivering highly effective performance and its importance to the Education Service.
能不能帮帮忙啊？不要直接google翻译的。
