Developing educational and testing material stretches the imagination and exercises every writing muscle. Careful attention must be paid to each detail, as a single mistake can discourage the learner. To keep things interesting, the content must be diverse in terms of context. It must also be clear, concise and consistent. And it has to match the learner's capabilities while at the same time enabling them to advance.
Daniel Warriner started writing educational material for students and teachers in the 1990s. Around that time, he contributed to a series of textbooks for schools in Tokyo and helped with the development of a curriculum for the Peace Boat. While a lot of the educational content he writes these days is for TOEIC preparation guides, he also produces Eiken tests and other types of material.
Many of the publications and other projects he has worked on are shown below.
