I just watched a great video (a kind of short documentary) about two educators who strive to afford better education for their students in a college in Red Hook (a neighborhood in Brooklyn).
The video makers made an interview with one of the students' mothers :
The mother (crying next to her son): I've never cried like this ... I've cried like this one time ... when I had to leave him back, and I cried, I cried, I cried, that was the hardest thing in my life, to tell his teacher to leave him back ... in third grade [...] I told his teacher to leave him back, because he was struggling.
I've looked up the meaning of leaving someone back on the web but, I didn't find a relevant meaning. Here is what I think it means :
The expression, leaving someone back (in the context of the interview): is to make someone stay in their current grade even if they succeed.
- What do you guys think the meaning is? And is it common to use this "phrasal verb "?
You can find the video I saw the phrase used in here.
