With artistic talent, determination and relevant experience, you may be able to develop a career in illustration without a formal qualification.
However, most professional illustrators have a degree, either in illustration or in another art-related subject. Entry requirements for degree courses often include a recognised art and design foundation course.
You may also be considered with other relevant qualifications and could be accepted on the strength of your portfolio. You will need an up-to-date portfolio of your work to show to prospective clients. You may be able to find a portfolio-building course at a local college if you need help putting your work together. You could market your work by contacting relevant companies directly.
You can find advice about getting started as a freelance illustrator, lists of publishers, and other useful information in The Writers' and Artists' Yearbook, published each year by A & C Black. You should be able to find it in your local reference library as well as in bookshops.
If you join the Association of Illustrators (AOI) you can have your contact details and samples of your work displayed on the website.
If you work as a freelance illustrator you will usually sell your work through an artists' agent, who may take a commission of up to 40%. You can find lists of agents, publishers and specialist organisations (such as those for children's books) on the AOI website.
