Quick canon question

[Kelley]

Since I'm so behind on the main list, thought I'd toss this question 
over here.  I'm reading the Quidditch discussion from nearly three 
weeks ago (!), and I can't recall--is it stated definitively in canon 
that Alicia and Katie are sixth years by GoF?  I'm clear that OoP 
will be final year for the twins and Angelina, but was not 
remembering that A and K were also going to be seventh years.  For 
some reason, I was thinking that perhaps they were only fifth years 
in Goblet.  Anyone?
