No MUN delegate can be a good delegate without practice. Sri Lanka Model United Nations, being Sri Lanka's largest and foremost MUN conference caters to both; novice and experienced MUNers. To familiarize delegates with committee procedures and with the head table, SLMUN holds practice debates before conference. During these practice debates, delegates are given an insight into how conference will be like and are able to clear all their queries through the head table and also get feedback on their performance. Due to this, they become better delegates at the conference.

This year's practice debates were held on 11th and 19th August at APIIT, Colombo 02
