Many nurses who qualified with a diploma can choose to upgrade their qualification to a degree by studying part-time. Many nurses prefer this option to gaining a degree initially, as there is often an opportunity to study in a specialist field as a part of this upgrading.[citation needed] In England, it is also much more financially lucrative, as diploma students get the full bursary during their initial training, and employers often pay for the degree course as well as the nurse's salary. However, from September 2013 onwards all students can only study at degree level, while diplomas are gradually being phased out permanently.[58]
