I think it's better if your friend take the prometric exam Check this site, http://www.sch.gov.qa/sch/En/scontent.jsp?smenuId=54
the exam in itself is $200 but would be great if trying to find employment, it's online and sites are assigned internationally, he/she can use this with any employer, and it is always better if he is hired direct from homecountry so he can be eligible for expatriate benefits, you know what I mean...
