Process writing focuses learners on the different stages and aspects of writing as they have been observed in good writers, and spend time on each, led by the teacher. These are; planning, drafting, revising, editing and considering the audience.

Example
The learners are at the editing stage of their writing work so spend time identifying problems and correcting them, with the teacher helping.

In the classroom
Process writing in its full form can take a lot of class time. Some parts can be done in class, such as brainstorming and discussion, leaving others for homework such as drafting.
