A good question, given that most parents are trying to get any and every edge they can give their children so that they can achieve success, but are sometimes overwhelmed by the task of finding the right person or company for the job. And as most people know, getting solid academic preparation from the start is critical in passing the big tests like the UPCAT or Ateneo's ACET.
For the most of our lifetimes, the answer has been either one of these two: You go to an established tutoring company like Ahead or MSA, and hope that their teachers have the right material and give enough attention to your child. Or you get a reference from your co-parents at school and your friends, so that you're sure that you have a really good tutor. But these opportunities come only so often.
The online revolution has changed things, however, and far from being present just in transport (see Über), in the Philippines, it has expanded to tutoring. The newly opened start-up Edvantage Learning, was one of the first ones to jump at the chance, together with My Private Tutor, amongst others.
The way they work, at least for the case of Edvantage, is that tutors are hired by the website and marketed to potential clients, then, after charging a small commission (presently 150 Pesos), they will arrange your first session from the tutor you selected, after which you're free to make separate arrangements with them with regards to how to teach, and how often you'll pay.
The advantage, so their website says, is that you don't have a parent company skimming anywhere between 10-30% of your tutor's income, meaning you get what you actually pay for, and that you get to have your pick of who you want for your child without having to ask every single parent our there about their personal experiences. It makes the whole referral and hiring process much easier from the parents' side.
Worth it? Most probably, since it saves you the time and effort for what is probably an ideal outcome. But whether it clicks with a very referral-dependent market is another matter entirely.
