The Scottish Qualifications Authority said it was optimistic about the future of the Scottish baccalaureate, despite teething troubles in its first year.
The body said it had received a raft of enquiries from schools hoping to introduce it next year.
But school-college partnerships may be key to its expansion in some parts of the country, it said.
Low uptake of the qualification and its lack of availability in schools that run few Advanced Highers have prompted concerns.
Of the original 246 entries, 70 pulled out - 60 from science and 10 from languages - leaving 153 studying for the science bacc and only 23 for the one in languages.
Lorna Grant, baccalaureate development manager for the SQA, said: "This year, everybody who has been involved in the bacc has been really positive about it - pupils and teachers alike ... Every teacher I have spoken to has really loved it." NEIRE.
