The post made by anna15 is fake. From a current staff member, who recognizes the username and writing style of the post, I have been informed that this user is likely the principal at the school, Carol Hutchinson. Also, the negative references to Chinese people being dramatic, rumor mongering, and unprofessional, are very much the demeanor of Carol Hutchinson.
The school, on the surface, may appear to be a normal functioning school. But in actuality, as one user put it, it is in fact being run in a Hitler-esque type of way. In a nutshell, most of the staff members hate Carol Hutchinson. If you were to befriend a staff member there, they will tell you that she is more concerned with maintaining power and not losing face than she is with providing support for the staff. As a result, there is not much unity or respect between Carol Hutchinson and the staff. You don't see these type of things when you visit the school and the administrative staff. You may not even see this if you are to visit a classroom teacher. It is only if you befriend a staff member will you begin to see the true inner-workings of the school. And this is absolutely very important when you decide where you want to send your child. If the current staff members are being lead in a Hitler-esque type fashion, then you will most definitely have unhappy teachers. Anyone can put a smile on their face and go to work. But an unhappy teacher, regardless of the qualifications, can only give so much quality under those conditions.
As far as the quality of the education, truth be told, that will mostly depend on the quality of the teacher in your child's classroom. However, administrative support is a factor in the quality. Being a for-profit school, the administration is forced to take costs into consideration. And it costs money for resources. And the resources available are absolutely pathetic. So pathetic that the administration resorts to begging for resources from the parents. There is no real Western-based resource kit available to staff members (resource kits in Western countries come with manipulatives, books, etc). So resources must come out of the pocket of staff members, or in the case of Chengdu Etonhouse, the pocket of parents who already pay high tuition. In order to maintain a healthy profit margin, Etonhouse will rarely pay for resources.
As far as the quality of the teachers there, that is going to be a toss-up. In a real international school and public/private schools abroad, every teacher including classroom teachers, art/music teachers, gym teachers, (excluding assistants and English teachers) is to have the proper teaching credentials from their home country. According to my source, that is also a requirement at Chengdu Etonhouse, but not strictly enforced. Some teachers there do not currently hold the proper teaching credentials from their home country. Some only hold a TEFL certificate, which is only suitable for teaching English. Anyone can get a TEFL certificate online, even non-native English speakers. Also some of the core positions are held by Chinese staff, which is done because the salary for Chinese teachers is a fraction of that of a credentialed foreign staff member. Basically an attempt to save money.
The positive reviews here on this site, which I suspect to be written by administration, do give one valuable piece of advice. Go to the school and see for yourself. If you are considering sending your child there, which I highly advise against, I agree with the positive reviewers that you should go and see for yourself. Go to the school, have a little tour, look beyond the surface, ask the right questions, look for the right things. Any for-profit school can show you the multitude of events and planning that go into a typical day at school. But not any school can make the day effective, fulfilling, and joyful. That will largely depend on the ability of the staff who will be working with your child. So asking the right questions is essential if you decide to visit this school. Ask to see credentials and current validity dates of any teacher who will be working with your child. Ask about the resources, where it came from, who bought it. Don't fall for marketing ploys. Events, extra-curricular activities, games, songs, whatever it is they throw at you is all irrelevant if the quality of the teachers is inferior.
With that being said, I will still offer my opinion and say that visiting the school is a waste of time. Look no further than the review posted by the user anna15 (which is suspected to be the principal Carol Hutchinson). For the sake of argument, let's say my source is wrong in their estimation, and the user is not in fact Carol Hutchinson. The user anna15 mentions she was a parent committee member and volunteer. The user then proceeds to say "Chinese are very good at drama and rumor mongering and gossip". Then the user says, referring to Chinese people, "They are very unprofessional people". This is the type of people at Chengdu Etonhouse who will be around your children. I've had the unpleasant experience of interacting with Carol Hutchinson. I was not impressed. She has been in China for several years now, and still does not speak a lick of Chinese. I guess she does not want to associate herself with such unprofessionalism. And the years in China have been unkind to her. Her profile picture on the website and her current state can show you a wealth of information.
Read the review of the user Baloo. The user Baloo also mentions some animosity in the Wechat group about the issues of the school. There is no unity. The user Baloo also says "At the end of the day, they know that this is the best they can get". Meaning, there is no incentive for Chengdu Etonhouse to spend money to further the quality of the education. But actually, this is a problem throughout all of China. The demand far exceeds the supply. And when that's the case, the supply becomes inferior and there is no incentive to rectify that.
There are other options in Chendgu. Yes, visit the school if you'd like. But my opinion is that you will be wasting your time.
