Hi Megha,
Usually for a 5 days training it's not possible to just participate just 1 day and would keep this day. For example HR050 is a 5 days SAP standard training course and it's not possible to say a person passed (participate) 1 day!
Participate can pass or not pass a training course based on company policy. For example if a person participate more than 70 % of a training s/he has passed other was not. You can specify this at follow-up(PV15 tcode).
Regards,
Omid
