The fourth type of Kaddish is Kaddish D’Rabanan. This Kaddish is recited after learning a portion from the Oral Torah. Although it is usually recited by mourners, it can be recited by anyone. For example, if a person makes a Siyum, completes a Tractate of the Gemara or an Order of the Mishna, he usually recites the Kaddish D’Rabanan, even if he is not a mourner.
