The shortlist of no more than four books and the winner were selected by three children's fiction writers, almost always including the latest winner.
The Guardian described the prize as the only children's book award winner selected by peers. The newspaper's children's book editor
Julia Eccleshare participated (from 2000 to 2016) in selection of the longlist and thereafter chaired the panel of final judges. In years to 2016, a longlist of eight books was announced in May or June, a shortlist of no more than four announced in September, and a single winner. The longlist was the foundation for a
summer program of reading, reviewing, and discussion. The U.K. publishers of eligible books entered them for the prize with a fee, although the chair may call for submission. The publication year is August to July of the current year, but May, June, and July books must be submitted in advance. Books originally published in another language were eligible in English translation for five years. Routinely, eligible books were entered for the prize by their UK publishers, as many as ten books each (2000) although chair Eccleshare also called for particular submissions. ==Honorees==
