It depends on the context. If the students are acting individually, then "are" is correct: Three-quarters of the students are failing the class. If you are referring to a single collective entity then "is" is correct: Three quarters of the students is an unacceptable number of failures.
If all students receive a failing grade in a class room it is usually considered the teacher's fault and the students will most likely be transferred out of the teacher's class and the teacher may even be fired.

No, but Yes. It depends how sucky or good your school is. My Highschool's Biology teacher had 75% of her students failing. But she didn't get fired.There is a lot more to this than just failing students. Teachers have evaluations and if she failed to address problems found in an evaluation that could lead to dismissal. If she is a senior teacher that is a factor, and if due process is followed in any actions against her that is also a factor. There are many things involved in this and each teacher is different.
