All of the answers sheets are digitalized in the high performance Kodak scanner. This secures the highest quality in the documented images. The dual digitalization (B/N and Color) allows us to make a double optical reading of the sheets.

Optical reading of the answer sheets

The engine of the optical reading is really the heart of all the system. It is consequence of several years of a mix team formed by ODEC’s technical and the IT (University Politecnica of Valencia). Roughly talking we can mention three engines of recognition that control and correct them offering as a result a totally trustworthy answer sheet.

“What the candidate has answered is what the system has read"

Digitalization of the heads

With personal data (anonymous correction). The head contains the identification data of the candidate. This head is separated of the body of the exam sheet and until its reading is not done it is not possible to know the identity of the answer sheets. Through this system the security and objectivity of all the process is guaranteed.

“This way the candidates have a total guarantee that their test will be treated with the highest objectivity, with no interferences at all. The same opportunities for all the candidates”
