Educating Rita or Educating Frank??

Coming to the end of the play, I think Rita has learned quite a lot. She's not only learned how to express her ideas somewhat better, she has also learned to be a better person, to judge others better. Frank has also learned that there's more in life that only what he wants from it.

I think the play ends with Rita cutting Frank's hair as a way to show us that both of them have grown as individuals. They are now able to share better and they can learn from each other as people, as friends, not only as teacher and student. Rita tells Frank he is a very good teacher, as he has helped her pass the exam by giving her all the tools she needed academically speaking. But she also thanks him because he also gave her tools to understand the world better. Having Rita cut Frank's hair shows that she can also teach him something about life, something related to be a better person
