Do all Buddhist schools give dharma names upon ordination?

I was glad to read in [MatthewMartin's answer](https://buddhism.stackexchange.com/a/1565/15) to another question that he'd be interested to know if dharma names are common to all Buddhist groups/schools/sects, or if there are any that don't give monks new names on ordination. This is something I've also been curious about. In addition, I believe the usual practice is for the teacher to select the name for his newly ordained pupil, which might represent a lesson to learn, or an encouragment, or a trait to focus on during the new monk's future growth. So my question is whether this practice is universal amongst Buddhists, or if there are any schools that follow a different tradition or refrain from dharma names completely,
