From the Starting Points window click on the Assistants tab and then click once on the Certificate icon.

You will be greeted by a Welcome screen.

 

Type your information in the placeholders, clicking the Next button on each screen.

 

 

The assistant will "walk" you through four screens to create one of several types of certificates. Choose from Merit, Appreciation, Achievement, Membership, Diploma or My Own.

 

 

Choose a border style on the final screen and then click the Create button.

The completed certificate is an AppleWorks Drawing document that you can further edit, add graphics to, and change type sizes and styles.

Have fun!
