"This helps us to ensure that the candidate has played or will be playing a meaningful role in a company," said an MOM spokesman in response to queries from The Straits Times.
Announced by Minister for Manpower Tan See Leng on Aug 29, the new pass, applications for which open up from Jan 1 next year, offers its holders flexibility to hold multiple jobs and start one or more businesses.
The spokesman said examples of outstanding achievements in the arts include receiving prestigious international or regional prizes for excellence in artistic endeavours.
Applicants for the pass could also have well-established careers in "enabling roles", such as managing top-tier talents.
"For example, a world-class and renowned producer could provide networks, collaboration, and opportunities which support the growth of local talent," said the spokesman.
In sports, suitable talents eligible for the pass include athletes, coaches, sports scientists and other sports-related specialists with a proven track record.
"They should be a good fit to benefit our broader ecosystem through their desire to contribute while pursuing their own interests," he added.
Meanwhile, those in research and academia, or science and technology, who are granted the One Pass would have demonstrated a high level of achievement in scientific and other academic research.
This includes "a proven record of impactful outcomes from research conducted, which may include international recognition of scientific and academic leadership".
The MOM spokesman also said workers who are already in Singapore may apply for the One Pass before their existing work pass expires.
After obtaining approval for the new pass, their employer should cancel their existing work pass before the new one is issued.
MOM also confirmed that there would be no cap on the number of One Pass holders.
Nonetheless, as the pass is benchmarked to the top 5 per cent of Employment Pass (EP) holders, it expects around 7,000 to 8,000 people to hold the One Pass, based on the current number of EP holders.
It added that numbers can vary over time, and it will monitor them closely when the pass is launched.
The ministry also said the processing time for One Pass applications "will be within four weeks for most cases", even as the EP processing time has been shortened to 10 business days, with employers able to expect either a definite approval, rejection or a status update if more time is needed.
