One way to get a sense of structure with the evaluation of student oral production is by using a rubric. Here's an example of a speaking rubric for an ESL program in a US elementary school system: RUBRIC and here's a site with programs to help you develop a rubric: DEVELOP RUBRIC
To create a rubric for a speaking activity such as retelling a story, you need to break the activity down into its most basic elements. For example, speech is comprised of vocabulary, grammar, pronunciation/stress/intonation, logical meaning and order, purpose, and in the case of the story, an element of cohesion. For the specific task, you might want to also consider the accuracy of the retelling, the amount of detail included, number or length of pauses and inappropriate filler noises, etc. Then, for each category, set the possible performance/assessment levels, for example, "excellent", "satisfactory", and "needs improvement". I prefer to work with a basic set of 3 as it is easier for me to break down a production into bad, so-so, and good instead of more subtle variations- although plenty of instructors use 4 and 5 categories.
If you do a Google search using key words like "ESL Speaking rubric", you should find many ideas to help you create a rubric that will meet your needs.
By the way, I would suggest recording the assessment either audio or audio/video because it can be hard to listen to content, mentally evaluate, and complete a rubric at the same time. Replaying the audio gives you time to better analyze the students' work and assess more fairly. Playing back the recording for the student who can then watch him or herself and compare the recording to the completed rubric assessment is a valuable learning tool as well.
