Version numbers for folder names are written as YYYYMMDD. This way, an alphabetical ordering of the folders lists them in chronological order.
| Directory | Description |
| (root) | Software main page, global.asa file for the development phase (since this folder is the root of the application). |
| admin/ | Pages for the administration sheets. The admin interface is not versioned. |
| (version#)/ | Main page, non-database pages. |
| (version#)/reading/ | Contains pages for the actual reading assessment process (instructions, passage, questions, results). |
| (version#)/reading/passages/ | Contains passages as HTML fragments. Filenames in the database refer to this folder. |
| (version#)/images/ | Images for the main area of the site. (Images in other sections should be put in another subfolder; for example, "reading/images" for pages in the "reading" folder.) |
