In Russia usually in general too most lawyers have professional education, and lawyers "from the street" is a rarity. But yes, if you don't have professional education (but have independent education) you still have the opportunity to work as a lawyer in a limited number of organizations (e.g. without professional education you will never be able to work as a judge, etc.), except if you get a job, you may not be able to present a professional diploma, and you will have to prove their qualifications in other ways This can reduce your competitive ability.

About system you describe, I can't evaluate it in terms of the presence or absence of fun, because I do not know what the result is achieved through the application of a verification system for lawyers, more precisely future lawyers, if I understood you correctly.
And it's actually my question is justified the use of such knowledge verification system future lawyers now, or, for example, you can dispense with the bar exam at least for those lawyers who are going to work in a little less responsible spheres, for example lawyers who work exclusively in the Office (never go to court), mostly work with documents, etc. or this exam must pass absolutely all the lawyers? I'm interested in your particular view on this issue)).
