When I wanted to take CELPIP, I was pretty nervous about the format and difficulty level of the test since there isn't much practice materials out there but it actually turned out to be fine. Here is my experience:
Registration: CELPIP is held every Friday and Saturday in most of the major cities and registration spots are usually open even a couple of days before the test date which is a big help nowadays with all these caps and process changes that are happening. The price is also $30 cheaper.
Practice: This is the part that was scaring me because there are not enough material out there to practice. There is a free sample test and two additional sample tests for sale. I strongly recommend to take the free test and buy the other tests if you are not short on cash. The reason is the speaking section of this test is 100% different from TOEFL and IELTS and it can catch you off-guard if you are not familiar with the test format even if you are pretty proficient with English. The other three parts are not that different and they resemble TOEFL iBT.
- The writing part has spell-check that underlines wrong words in RED!
- In the listening part the questions are sometimes hidden and you have to scroll down to see all of them. Make sure you don't skip any
Results Delivery: This is one of the nice things about this test. I got the results online in 7 Business days which is better than advertised (8 days). I called in advance and ordered my results to be shipped by courier as soon as they became ready. They post them by Purlator which delivered mine in 1 day and I got the results in the mail in 8 business days. They are mailed out from Vancouver and I live in Edmonton so the actual timeline for you will depend on where you live. The customer service rep told me I could even go to their office in Vancouver in person and pick it up.
Test Day: All the staff were OK but the room was too small and I had to have the headset on to be able to focus. You may find it a bit challenging if you tend to be distracted easily. This off course depends on the test center.
Difficulty: Different people have different ideas about how difficult these exams are in comparison with one another. I have taken TOEFL, IELTS and this one and here are my scores as a comparison:
TOEFL (2010): Reading: 29, Listening: 28, Speaking: 23, Writing: 28
IELTS (2012): Reading: 7.5, Listening: 8.5, Speaking: 7.5, Writing: 7
CELPIP (2014): Reading: 12, Listening: 12, Speaking: 10, Writing: 8
The other negative point is that this exam is not widely recognized and you would not be able to use it for any purpose other than immigration.
