Hi.
The WAEC requirement seems to be a new development, because I only noticed it last week as well. If you're using it for employment purposes try to verify that you're not limited to WES before you pay to another evaluation body.
If you're in Nigeria, getting your WAEC certificate sent to WES isn't as difficult as we all expect it to be. A friend of mine went to inquire last week and was told to get an affidavit, the certificate number, buy some stamps and a large envelope (all of which are available at the premises for purchase) , pay #10 000 for "confirmation" as they call it, and pay for shipment.
I haven't done mine yet, but I'm not in a hurry. I hope you're not in a hurry as well so I can update you with any new info I get.
UPDATE:
Things you'll need for May/June candidates.

Got to the fifth(5th) floor of the WAEC office to process your documents.
Things you'll need for GCE/Private candidates.
1. 2 passport Photographs
2. A copy of your WAEC result (buy the N500 scratch card and downlaod the result from their website. You need to know your candidate number)
3. An affidavit for confirmation of result (obtainable opposite the WAEC office in Yaba for N4,000)
4. An affidavit for attestation of result (obtainable opposite the WAEC office in Yaba for N3,000)

Word of Advice: Go in the morning from 9am. WAEC is a Government office similar to a ministry. You go there too early, you're on your own & if you go too late, same same.
