Ya. I am sure I have not earned any points for her education.You're welcome.
Remember that they ask you for these documents basically to verify that the points your claiming are valid, and that you're not misrepresenting yourself or your partner. Just like with the IELTS, your wife can opt not to take it, but then you won't earn those points.
Edit: As I tell you before, because I don't know what the requirements for the highschool diplomas are. Be sure to investigate if it doesn't need an ECA. If it does need one, then you'll have to calculate your CRS without it and update your profile removing it from your partner's qualifications. Or do the ECA for her University's degrees and claim the points.
and there is no requirement for high school verification, never heard from anyone.
So it should be good.
