It is not very common for lawyers to take the test of economists. This is mainly because lawyers and economics are two different fields. Although there is some overlap between the two, it is not enough for lawyers to turn to economics in general.

First of all, the lawyer's main job is to deal with legal affairs, including providing legal advice to clients, representing litigation and drafting legal documents. Economists are mainly engaged in economic analysis, policy research and enterprise management. Although lawyers need to know economic knowledge in some fields, such as finance and trade, they don't need to go deep into the system like economists.

Secondly, lawyers may face some challenges when they take an examination of economists. On the one hand, economics is a relatively complex subject, which requires systematic study and mastery of certain mathematical knowledge. Lawyers may lack background and experience in this field and need to spend more time and energy to study. On the other hand, the career development path of lawyers is usually clear, while economists need to face more career choices and development directions, and need to consider whether their interests and career plans are suitable for turning to economics.

Of course, some lawyers will choose to obtain an economist certificate to increase their professional competitiveness or expand their professional fields. But this is not a common situation and needs specific analysis.

In short, it is not a common phenomenon for lawyers to test economists, mainly because there are great differences and challenges in the two fields. But the specific situation needs to be decided according to personal interests, career planning and development needs.
