The grading environment should be quiet, with appropriate lighting, and grading undertaken on high-quality computer equipment and screens.

A grader needs good pattern recognition skills and attention to detail.

Graders should adhere to minimum standards and numbers of grades as required by the NSC.

A grading scheme has been formulated comprising a retinopathy grade (R) and a maculopathy grade (M).

Graders should check image quality, and use a step-by-step grading method which may also use image manipulation.
