Form layout should be easy for the interviewer to see and understand. For this reason, it's usually best to place fewer items on each form that you might with a non-CAPI application. Also, remember that screen real estate is limited in a CAPI application, since question text will occupy a large portion (sometimes up to half) of the top of the entry window.

Consider breaking your application into a series of sections, each of which deals with a topic (earnings, fertility, etc.). One or more forms are then used for each section's questions.

Avoid scrolling in CAPI applications, since this prevents the interviewer from seeing the entire form (or roster). Also, the interview environment—laptop, maybe no mouse, possibly poor lighting—often makes scrolling cumbersome.

Also, it is good practice to gather the names of all household members at the start of the interview. Then the interview can cycle through each member. Doing this minimizes the risk of accidentally omitting household members.

Try to limit the size of your forms so that the interviewer won't have to scroll them. When developing your application, be sure to test your application using the screen resolution that will be on the laptops used in the field.
