The Investigate Officer Reports wrapper mission got buffed beyond all recognition in the latest patch, and it now gives SERIOUS Captain and Bridge Officer SPs. IIRC, it now gives between 1,500 and 2K of each type. Previously, it was giving 300-400 points of each type at VA.
Noobs, here's how you do it:
Open the Mission window (to hail for missions). Choose Investigate Officer Reports. This is the wrapper mission.
Now click on the tab for player-created content and choose three Foundry missions that sound interesting. to you. If you don't employ any search or filter terms, then the most highly-rated ones will be at the top. Choose some and pick them up.
Now go do your three chosen missions. When you're done with them, you'll be done with the wrapper mission. Hail the contact and collect your 1,500-2,000 SPs.
If you can't decide on any Foundry missions, then locate The Nagus List here on the fora and choose from among them. The Nagus has an excellent list of highly-recommended Foundry missions that are worth playing.
