Aaages. I took my ATCL in a June diet of exams and got the certificate in December, I think (problem with the embossing machine

) - LGSMD came through a little more quickly with the exam in November and the certificate arriving in March. I thought the packaging of my certificates was actually the showy bit, rather than the certificates themselves, and I do think they are attractive enough to hang up. They are a nonstandard size, a little bigger than A4, but very nicely written.
