Working for high quality alternative ways of evaluation in Higher Education
Quipu-Katrai is a network of teachers/lecturers and education researchers, for mutual collaboration in evaluation and pedagogical activities. This is to be done using the SiDEx-Omega software, designed to create and manage parametrized tests (either virtual or presence-based) in a systematic, flexible way; at the time of providing automatic grading and high levels of secutiry against fraud.

Integral Calculus Sample Test. The PDF document contains a sample test for Integral Calculus in its final form. It is a printing strip for 6 students/tests. Here, many other elements appear
The student's personal information: name and ID number, for identificacion purposes.
The student's location: seat number and (testing) room, for organization of the event.
Inventory information: group/section the student belongs to and the codes in the upper left part. This information is introduced for quick and accurate management of the physical tests. They make each test traceable together with other inventories created by the system to that end.
It adds at the beginning a table where the students should write the answers. This protocol is introduced to speed up the digitalization process of the answers for later automatic grading.
