Customise response boxes to reflect required answers and reduce completion errors. If asking for a persons date of birth, it makes sense to provide a box with the exact number of required digits and an example or guidance note to explain the format that the date should be entered in (DD/MM/YYYY).
Also make sure that you make good use of features like running headers and footers on every page to remind people what the form is, where they are, and what page number they are on.
Many assume that making forms shorter makes them easier to complete. Though shorter forms might be cheaper to produce initially, if the reduction in content results in user confusion, the cost of resolving completion errors form fillers make as a consequence can significantly outweigh any initial savings. In general forms do need to be as short as possible, but never at the expense of clarity and usability.
Use appropriate response mechanisms. Paper forms have the disadvantage that users can miss, or simply disregard, an instruction. For example, only tick/check one box from a list of 15 or 20 options.
