I was going through the rules and its states that classification is limited to the level indicated by the National List (so binomial nomenclature), however, I have seen tests in which family or order is asked for. Am I misinterpreting the rules?
Well people have asked it on tests before, so you should know it.
The rules may say so, but the rules don't write the test. According to the rules for Fossils, the Smithsonian handbook is the official guide for time ranges, but most people in the event (event supervisors included) don't even know that's in the rules.

I'm only concerned about the literal interpretation for nationals seeing as how the event supervisor is most likely the same person who wrote the rules.

See page 3 of this document: http://www.msuextension.org/invasivepla ... itetop.pdf
(Note: they use old taxonomy for the two: ("Globe-podded whitetop (Cardaria pubescens)"=HAIRY WHITETOP) ("Heart-podded whitetop (C. draba)"=WHITETOP))

Also see the 3rd and 4th images of this page: http://www.co.stevens.wa.us/weedboard/o ... itetop.htm

The spotted knapweed behind my school has started to flower.

Thankfully it was only 2 plants, so hand pulling was pretty easy.

In other news, Japanese Spirea has been in bloom here for the past few weeks.

Isn't St. Johnsworth able to be classified as a somewhat helpful invasive, seeing as it's used in some medicines? I'm scrolling through these posts and I'm jealous--the only common invasives in my city are Japanese Honeysuckle, Alligatorweed, and the occasional Medusahead.

Well yes, but in this case it is not being cultivated with proper measures to prevent its spread, it's just growing freely in an extremely eroded part of my yard. The same thing kind of goes for Japanese Spirea. The plant in those two pictures is an ornamental in flower beds, which isn't a problem (yesterday evening I also came across some growing freely out in the woods, which is a problem).
