Introduction to writing custom response processing rules

As mentioned in the last chapter, this is the step which involves creating a custom response processing rule for the item. This rule will do two things: 

• connect each of the interactions in the item to the corresponding variables which Ian created in the last section
• calculate the score values for the whole item

The rule needs to be written in html code. Rules can be prepared in an external html editor and then pasted into the editor used for this purpose in TAO, or written straight into the editor in TAO.
