Dragonborn Sorceror starting skill proficiencies?

One of my party rolled up a Dragonborn sorcerer (Both race and sorceror archetype) in a session and after going through the race, class, and background (outlander) she ended up with just 4 skill proficiencies, 2 from her class and then 2 from the background. Have I missed something here or is this about right for a sorcerer?
