SINO (Student In Name Only) is new, but it could catch on.
"Pushout" has long been replacing "dropout" in education lingo.
20 May 2005, New York Post, "Warehousing Kids" by Marc Epstein (dean of students at Jamaica HS), pg. 29, col. 1:
SCHOOLS Chancellor Joel Klein recently observed that chronic truants who never show up to class should be awarded a grade of zero rather than the customary 45. Mr. Klein's comon-sense view, if applied system-wide, would reveal that large numbers of students are in fact "SINOs" -- students in name only.
(...)(Col. 2 - ed.)
Dropouts are now called "pushouts," implying that our schools are unfairly pushing kids out the door. Lawsuits and consent decrees have made it all but impossible for guidance counselors to suggest that a 19-year-old with only a handful of credits has no chance of completing graduation requirements at their current rate of progress. The official response has been to have a massive truancy and attendance program that guarantees that our school officials can't be accused of making these SINOs unwelcome.
(Col. 3 - ed.)
The results have been disastrous for good and bad kids alike.

Not a dropout, but a pushout, as Eddie described it.

Adam Clayton Powell, the Harlem globe-trotter, boviously enjoyed presiding over his committee on education and labor when it dug into Chicago's explosive school system.
Martin Luther King, who had been demonstrating against Chicago School Superintendent Benjamin Willis, prodded Powell into conducting these hearings. Powell, however, needed no real prodding and promptly called Prof. Philip Hauser, an anti-Willis witness, who stated that 95 per cent of the students were promoted whether they deserved to be or not.
"I would call that a pushout, not a dropout," interrupted Powell.
24 November 1966, New York Times, "A DROPOUT STUDY BLAMES SCHOOLS," pg. 58:
"The term dropout might often be changed to pushout," said Dr. Robert Vintet, associate dean of the university's School of Social Work.
