The problem of traditional placement class process are
teachers have to identify and find useful information in large
databases manually and it is a difficult task [1]. A very
promising solution to facilitate the placement class process
is using knowledge discovery in databases techniques or
data mining in education, called educational data mining,
EDM [2].
But, educational data and problems have some special
characteristics that require the issue of mining to be treated
in a different way [4]. Hence, it need to determine the best
method for the placement process of students.
There are several important differences and/or
advantages between applying data mining with respect to
only using statistical models [5]:
1) Data mining is a broad process that consists of several
stages and includes many techniques, including statistics.
The knowledge discovery process includes the steps of preprocessing,
the application of data mining techniques,
evaluation and interpretation of results.
