The most common practice among publishers is to arrange for trial use of their new textbooks at schools, for which they pay a "trial-use fee" to the principal. At many primary schools, new textbooks are put on trial use after final textbook decisions have already been made.
廠商為了營運，最常見的是以安排新版本試教的方式，發試教費給校長，很多國小的情況是，幾乎在試教的同時，教科書版本也已經決定。
