The aim of automatic essay assessment is to prevent plagiarism to the students in some cases the students when they are given the assignment they are copying from the internet or books and it is difficult to figure out the problem by manual work, then by using this type of software it is easier for teacher to find the problem.

Advantages of automatic essay assessment can be categorized into two parts to teachers and to the students
To teachers

Not only that but also it help to make a critical final grade and they might be to objectives set. Moreover make always the teacher consistency and avoids the biasness to his/her students
To the students
The automatic essay assessment makes the students to be in high challenge to think critically that their essays will be assessed by the software so they would have to write their essays which would meet the criteria which are set by their instructors. The feedback which would be back is real and relevant to what they did in their essays. More than that it looks at the qualities of the students work and not comparing with others because each essay is assessed as it is so reflects the learning process of that particular student.
Problems
Wherever there is good comes also bad things foristance the costs to be encountered by making the software which could identify those criteria is very high such that the schools can not avoid to purchase them. As long as the teacher are reading many essays they get many ideas they the use of soft wares to assess them many lead to the reduction of thinking capacity of the teachers. Not only that but also they need the high qualified people in Information technology to set up and run those machines.
Challenges
In most cases the Tanzanians students at lower level do not know how to use the computer, they simply write on hard copy which can not be lead by the computer so we berg to those who can make a software which can even assess the essay in hardcopy. Also the machine can assess each and every thing which appear in the essay and give back the whole essay with those corrections.
