{\TeX\ in educational institutes} {Yasuhide Minoda} {Tokyo Educational Institute (Tetsuryokukai) is a preparatory school specializing in the entrance exam for Tokyo University. We use \TeX\ for our texts, workbooks, other handouts, and even for internal documents and memorandums. We used to use other software, but we swiched to \TeX\ and made our original documents (over 100,000 pages) into \TeX\ files over the last few years. In Tetsuryokukai, we now have over 200 teachers, with various levels of computer skill, so in order to introduce \TeX\ we: %\begin{itemize} \item developed related software (automatic installer, \TeX 2img and so on), \item prepared various style files, \item educate and motivate teachers. %\end{itemize} In this presentation, I would like to present what we have been doing in our company. Our company can be an interesting and helpful example of introducing \TeX\ throughout an institution, especially in the field of education. }
