Started and didnt finish, as did many of my previous colleages. Quality was poor if you are already in the industry with a reasonable amount of knowledge. The two areas where it fell down badly for me were in areas I know a good deal of detail about. Met, Airport operations, and environment. Other colleagues found major problems in the flying sections. They would potentially indicate to an employer that you have some knowledge of the subject matter, especially if you are young/new to the industry.
No they are not an industry recognised qualification as such, and neither is the Glasgow course which also has its fair share of quality problems. Use the search function here and you'll find plenty to read on them.
If you can stretch to it try and do an FAA dispatchers license. Its industry recognised worldwide, so you can work overseas with it. Might be expensive when looking at it in isolation, but it would give you a massive advantage over anyone with a Avtech2000 or Glasgow piece of paper when applying for a job in the UK, and even more so overseas. So if you're self funding, take a bigger loan and get the 'real' qualification, over the years it'll pay itself back with interest in terms of salary and opportunities. Its not an easy ride by any stretch of the imagination, but if you want a career in ops, the TAA ticket is the only qualification that matters.
