Find a private tutor in Phnom Penh whose school and degree were checked in person. Search by subject and grade — finding and contacting tutors is free. Every verified credential on a profile was seen by somebody from Ousa — the degree in hand, the certificate, or the teaching post confirmed with the school office. A tutor cannot type their way up the list. What was checked is what decides the order you see, and it sits in its own section on every profile, apart from anything the tutor wrote about themselves. SUBJECTS AND LESSONS Maths, physics, chemistry, biology, English, French, Chinese, Khmer literature, IELTS, TOEFL and SAT preparation, Bac II revision, piano, guitar, coding and more — for the Khmer national, Cambridge/IGCSE, IB, French and American curricula, from primary school to grade 12. Each listing says whether lessons are at your home, at the tutor’s place, online or a mix. HOW IT WORKS Search by subject and grade. That is the whole search. Two answers, and a ranked list comes back — not a set of filters that returns an empty page. Read the credentials first. Each profile says what Ousa checked and what it has not, in plain words. Tap "Show contact" when you want to talk. A tutor's phone number and Telegram handle stay hidden until then, and you talk to them directly. Ousa does not sit in the middle, take a commission, or handle your money. Save the tutors you are weighing up. The ones you contacted stay on a list of their own, so you can find them again after the call. Reviews come only from people who actually contacted the tutor. If nothing matches, tell us, and we will message you the day a tutor joins for that subject. FOR TUTORS Listing is free and verification is free. You can never buy a badge, and you can never outrank a better-verified tutor. That rule is what makes the badges worth having. If Ousa built your profile, claim it with the link we sent you and it becomes yours to edit — your photo, your subjects, your certificates, from your phone. SIGNING IN A one-time code to your number, or Telegram, Apple or Google. There are no passwords to set or forget, and you can delete your account from inside the app. IN KHMER, ENGLISH AND FRENCH Every screen, and you choose which from the settings tab.
