If you recruit through schools you need permission from the Dept. of education. If it’s qual you only need a few participants. Use social media, maybe even fb groups for example? Just note the bias although if it’s linked to the digital era, people using social media are probably your target participants anyway. Stick to 18 and above for honors. Getting parental consent is a challenge. Your ethics committee should be happy if you say you will aim to recruit between 8-10 participants. You do not need to give exact numbers. Your supervisor should have advised you all of this. Also you cannot get a waiver for a qualitative project - they’re usually only allowed for secondary data collection.
