I am looking for an ESL placement test that covers CEFR Levels A1 to B1. I have already considered PET and KET, but they cover a different range. Can you help?
I've been using OOPT (On-line Oxford Placement Test) for about five years. It has a good technological platform for data management and evaluation. I believe it suits your needs. In addition it is one of the cheapest on the market (around 18 dollar each licence). I hope it works for you.
The British Council offers a very good test which is suitable for the level you are interested in, namely "The Aptis Test". I cannot provide you with a sample, but you can go to the site and see a series of samples. The good thing about the test is that one can order a customized version of the test according to the particular needs of your students.
