Over the years I bought 4 complete sets of American Headway second edition, plus books for my students. Just the sets cost around 600. The teacher's book, student book and workbook. The teacher's book came with a code at the back of the book to use the TRC (TeacherResourceCenter) with a website at oxfordtrc, used for interactive teaching. I have used it for years. However, in 2019, I had issues. I was not able to open the site, because it was parked on GoDaddy. I contacted the Digital Resource Person and after much delay, OUP got it up again and stated that "others" had problems too. Then April of 2021, I tried to use it again to no avail. After literally 50 emails, I was told that the site was decommissioned and during these emails with all my screenshots, they started to take out the link of the teacher resource center and replace it with a Teacher's Site. I was offered the 3rd edition, thinking it was the same, but it was not. It had few resources and needed a lot of registration for my students and myself and offered only 1 video and listening, none of the other resources from the second edition were available, which OUP is STILL promoting. They story goes, why fix something that is not broken? It troubles me that we pay for books, that include a service and then that service is stopped. Secondly, what is worse, is that OUP is still promoting American Headway second edition on their site here- American headway second edition level 1, 2, 3, 4 or 5 stating all the resources for the teacher's resource center that do not exist. Additionally, all over the internet you can find this edition for the teacher's book clearly showing the white circle on the book for the teacher's resource center. Amazon and many other book depositories even in the UK are still selling the teacher's book. Some for hundreds to thousands of dollars, if you dig a bit. Totally unethical and just bad business. Don't confuse the Teacher's Resource Center with Teacher's site lower to the right, which was the youtube video showing how to access the site. Here - it clearly shows the teacher's book WITH the white circle stating the resources available. Can’t include links on this review but you can search amazon for american headway teacher's book level 4, which is purple or any of the other levels. Plus american headway 2nd edition on youtube, which is now a private site. On this site it states this, which is no longer available, but still being promoted by OUP and those that have bought multiple levels are left out in the dark. -Now, American Headway Second Edition adds a new generation of digital support to that classic methodology. If you check out on amazon for the purple level 4 teacher's book the publication is in the year 1657, yes, you read that correctly and is being sold for as much as $569 dollars but with no actual resources! Really?! This is absurd. Bad business OUP. I even called customer service in the states in NC and the representative was not aware that the AHW ditigal resource center was no longer available. When I said I was going to file a complaint, he and the person from the UK, never responded again. Shameful. Again, here stating on the oup site for this edition states -Top of the list of new resources is the Teacher Resource Center. It's a password-protected bank of online resources which includes images, animated grammar PowerpointRG slides, video, worksheets, and more. With a fast-find browser function, it's quick and easy for you prepare lessons your way. Find out more at American Headway Second Edition also includes a new emphasis on testing to help students prepare for standardized international exams such as the TOEFLRG iBT. This includes new Spotlight on Testing lessons in the Workbook and access to a complimentary online practice test via the Student Multi-ROM. I am marking the box to let OUP know of my complaint. I have all the screen shots showing that the TRC were removed and more. I am filling this review with hopes that someone will put a stop to this and or file a consumer report. I tried to in the UK as many book stores too are still selling this edition, but the agency said I could not because I did not live in the UK. I know that there was a law about 5 years ago stating that buying a product with digital services included, but if the provider did not continue those services, it is against the law. Thank you Trustpilot for allowing us to warn others.
