Its called learn new skill day for a reason, skills 1-4 count towards the completion after 5 they are no longer new.
Skills that only go up to 5 only counts from 1-3.
New skill day requirement to count: Acquire new skill or gain a skill level in a low level skill.
I don't even think research and debate is actually a skill, not sure what you would use it for except for college, never played the college careers so I can't really verify if its used in the new careers that came with DU.

What expansions, game packs, and stuff packs do you have installed? Get Famous, Seasons, Get to Work, City Living, Spa, Vintage Glamour, Cool Kitchen, Spooky
Steps: How can we find the bug ourselves? Create or be live on "New Skill Day" with Seasons pack. Try to complete a new skill or raise an existing one. *Some Sims are able to complete this but not all*
What happens when the bug occurs? Some Sims are able to complete this action but usually, when a Sim raises a skill level or starts a new skill, this doesn't reflect a completed accomplishment for the holiday "New Skill Day." Also, the raising of the skill doesn't appear to be moving any faster than normal.
What do you expect to see? When a Sim is raising a skill or has completed a skill, I expect to see the holiday accomplishment. I also expect to see skill levels rising faster on the "New Skill Day" holiday.
Have you installed any customization with the game, e.g. Custom Content or Mods? On console - never used.
