The path to become an art lecturer varies depending on where you wish to work and exactly what kind of “lecturer” you want to become. In the US, a lecturer is typically anyone with professional or personal experience in a given subject who gives public speeches on that subject, and so you need only become an expert in artistic works. A lecturer in the UK, on the other hand, is an instructor at a university and is typically working toward a professorship. If you want to become an art lecturer in the UK, then you should complete an undergraduate and graduate program in art, and work your way into a lecturer position.
To become an art lecturer in the US requires little more than experience in art and public speaking. A lecturer is typically someone who gives public speeches and provides information to others regarding a particular subject. If you want to become an art lecturer, you should have a sufficient background in art to be considered an expert, which may require an extensive education in art or professional experience as an artist. You should then gain experience as a public speaker, usually starting small and taking on larger engagements.
If you want to become an art lecturer in the UK, however, then you are likely to need a great deal more education and experience in artistic matters. In the UK, the term lecturer is used in much the same way that assistant professor is used in the US and Canada. This means you typically need to complete a great deal of education to become an art lecturer. You should complete an undergraduate program in art, or a particular field in art, and then complete a post-graduate program in art, culminating in the completion of a thesis or dissertation.
Once you complete the education necessary to become an art lecturer, you can begin looking for opportunities to begin lecturing at a college or university. These positions can be quite competitive, so you should do as much additional work in the arts as possible to gain more experience. You should also focus a great deal of time on producing new and original works, either artistic or critical, and having your work displayed or published in well-regarded journals or other publications. This can help you become an art lecturer, as publication and ongoing research are typically both very important aspects of lecturing and eventual professorship.
