Spend your $2500 Elsewhere

For starters, CETP misleads you about where your $2500 application fee goes.
This is part of what is stated in the "Program Details" page of their website,
"WHAT’S INCLUDED IN THE TEN-MONTH PLACEMENT FEE, your fee goes toward":
"Full health insurance through host country" - this is incorrect. You pay your own health insurance via deductions from your teaching salary.

"Social events and teacher training classes" - the only teacher training class I got was during orientation, which for me was just a review of strategies I already use as an experienced teacher. Social events?? I think I learned about 2 (by reading the CETP Facebook page) for the entire ten months

"Monthly teachers’ newsletter" - I never saw one.

"Ongoing support from Director in the host country, and from Program Director in US" - I would have to give this one a no. I rarely heard from the Hungarian director, either by email or by phone, although when I needed her for a medical situation I had, she drove me to two of the appointments and we had delightful conversations. I had a specific question about paid time off for holidays/vacation that I emailed Mary (the U.S. Director) about and she didn't think we got any - although at the end of the year I got paid for 12 days of time off I hadn't used during the school year.

In terms of your placement - your experience will depend almost entirely on your contact teacher (the person or persons at your school who help you when you have problems with your apartment or if you need some support at your school). Although my contact teacher told me often that she had been "doing this" for 10 years, she was rarely helpful and actually said to me twice when I needed help, "That is not my job." She took several entire weeks off from school to take her own holidays, (blaming it on her bad knee - but she actually told me for one of those weeks that she was going to Israel), but never let me or the other CETP teacher at my school know. The school was dysfunctional from the top - the headmistress never acknowledged my presence (even when we passed in the hallways, she averted her eyes). I expected to make friends with the teachers like I had when I taught in Honduras and Guatemala, but only one teacher ever invited me to go out with her.

When you read other reviews - BEWARE!! I notice most teachers talk about how wonderful the country is (it IS wonderful) but rarely mention the actual teaching situation. I talked to about 10 teachers during the year and they ALL said the same thing...the behavior of the students is atrocious and disrespectful. I understand that during the first few weeks they might be testing your endurance and your patience, but until the last day of school, my students talked constantly, used English cuss words to get my attention, fought with each other and were often bullies to other students. It is hard to create your own culture (what you will tolerate or not tolerate in the class) because you and the students move classrooms every day and there is the general chaos that comes with taking your students to different rooms each day that aren't really theirs (or yours). In my school, there were no immediate consequences for bad behavior - the student got a black mark in their exercise book, and if, at the end of the year, their "homeroom" teacher decided they had enough black marks, their grade might reflect it. These black marks did nothing to change their behavior and of course, their grades didn't suffer, and they knew it.
My advice - take the $2500 you would have spent on the application and go to Hungary for 2 or 3 months! Hostels, food, trains and bus travel are cheap.
