"Assessing home languages is not important because they are not part of the school curriculum - there's no point in having a diploma in Lingala, for example."

"Assessing home languages may be useful for "major languages" / languages with "official language" status. It is only useful for languages with a national or international dimension, not for languages which are local."

"You can't assess languages that aren't written. You can't assess languages that vary from region to region."

"Assessment is used to check on learning. Assessment is useful for introducing a standard."

"You can't assess something that hasn't been explicitly learned."

"Assessing oral competences is complicated, difficult and time-consuming. It's impossible to assess home languages in their spoken form."

"To assess home languages, you need experts."

"It's easier / simpler to assess knowledge than to assess competences"

"There's no point in assessing ... in a dialect of Arabic, for example."

"If the learner doesn't write his/her language, he/she can't have a level."

"Mastering the language is everything: you have to know how to speak and write."
