STUDENT counselling organisations have strengthened their hotline service by adding more lines, counsellors and volunteers to meet the expected rush of calls when the HKCEE results are announced today. The Hok Yau Club has set up a strong team of over 100 counsellors and volunteers to manage its 25-line service during the 12-day operation. Last year, the club put up 22 lines, with about 19,000 calls coming in. ''This year, we have added more lines and volunteers, so that we can pick up more calls and provide better service,'' Hok Yau Club student counselling centre director Ng Tak-kay said. The volunteers, mostly matriculation or secondary school graduates, have received training on counselling techniques and Form 6 admission information. ''We expect more enquiries on Form 6 admission, as in past years they top the enquiries,'' Mr Ng said. The service, which started last Saturday will end on August 17. It runs overnight from now until Wednesday. The hotline number is 503-3399. Meanwhile, the club is distributing the ''Prospect Guide'' to HKCEE candidates. The free booklets contains detailed information on Form 6 promotion and Form 5 repeat. The 100,000 copies can be collected at most schools, youth centres, large bookstores, the Labour Department Careers Advisory Service Section and Hok Yau Club. Also, the Handbook on Education and Careers will be sold at the club at $70 per copy.
