Test & Training
Test & Training
Test & Training (TAT) and the international version iTAT are the Internet-served monthly quality assurance and training-support system for readers (graders) of diabetic retinopathy who work in systematic Diabetic Eye Screening Programmes. It is equally useful to new or experienced screening staff and to staff wishing to improve their skills in the detection of diabetic retinopathy from ophthalmic images.
The system provides graders with access to sets of retinal images from 20 eyes and identify and classify the retinopathy features present in the ‘ground-truthed' images. Each set of 20 cases is randomised at the point of delivery, so no two people see cases in exactly the same order. After each month-end, graders compare their responses and feature-list with the system results and the results of their local and national peers.
There are also over 40 training sets that graders have unlimited access to. The guide grades for these are immediately available allowing graders to review and compare their answers straight away, to increase and enhance their grading knowledge and skills.
Who is it for?
Test & Training is utilised as the mandated on-going monthly external quality assurance testing environment for all grading staff who work in the English NHS Diabetic Eye Screening Programme (NHS-DESP) and is currently used by over 1000 NHS-DESP users each month.
An international version of Test & Training (iTAT) is available to users from outside England. The iTAT system can be easily translated into almost any language (a Chinese Mandarin version is already available). This version is currently supplied to graders in China, the Republic of Ireland, Bangladesh, United Arab Emirates, Jamaica, Iceland, eSwatini plus many others.
