Abstract  
The relevance of the problem under consideration is determined by necessity to aware the role of the school grade in educational  
process, phsychological conditions in the development of students’ attitude to the grade as a sign of positive performance in the  
course their studies. Assessment, to a certain extent, is a complicated and deep process that includes not only registration of  
quantitative and qualitative indicators of the knowledge accumulated over the school years but also the ability to implement it in  
practice. Besides, assessment implies student activity, aspiration for learning, as well as motivation to study. The purpose of the study  
is to reveal the relationship between learners’ attitude of different educational levels to the school grade and their personal qualities.  
The key method of the research is empirical revealing the correlation of students’ attitude of different age groups to school marks,  
their personal qualities and anxiety level. The result of the research work proved the existence of quantitative differences in the ideas  
of students of different age groups about school grades, their understanding of the essence of estimating process at school. Besides,  
some significant interrelations between learners’ attitude to school grades and their personal features and anxiety level were revealed.  
The conducted study of psychological features of students’ attitude to school assessment has stated an urgent necessity of greater  
attention from the part of teachers and psychologists to the problem of giving marks and has justified the relevance to work out and  
introduce renewed criteria of school assessment.

standards, while assessment is a characteristic of results of an

undertaken activity achieved in the process of learning (4).  
The problem of assessment is in the focus of attention  
and is constantly discussed in pedagogical and psychological  
literature (2,4,6,28). On the one hand, the grade is part and  
parcel in an assessing effective activity, but on the other  
hand, it does not reflect quality of the learning process and  
can often perform a negative effect on children’s cognitive  
work (11, 24).  
Traditionally one of the most topical problems of school  
training is the problem of formation of study motivation of  
learners where one of the impulses to get knowledge is  
assessment and a mark (3). One can’t exaggerate the fact  
saying that this current issue has still remained a burning  
pedagogical problem. The notions “grade” and “assessment”  
are basically different: the grade, or mark is an indicator of a  
learner’s knowledge, its level, established by the national  
From the very beginning of schooling a child has to  
endure pressure of the mark as it hasn’t been a simple figure  
indicating the quality of a performed work, but has turned  
into a self-target (27, 32). And how a child worked, moved to  
the target, what knowledge he got, how he learnt and used all  
this in practice have lost its significance. Suffice it to mention  
L.S. Vyigotskiy (25), once he noticed that the mark was so  
allien to the learning process that it began to dominate over

the whole studying and even ruined the cognitive work. As  
the result, a child begins to study for the sake of a good  
grade, not for getting knowledge (6). Psychological effect is  
aggravated by the fact that teachers are often unaware of how  
this or that student responds to a mark and how it affects  
his\her personal qualities (28-30).  
because children due to their age, can’t fully aware of the  
criteria of assessing knowledge; thus they, to a greater extent,  
orient themselves to an outer component of the grade (8).

Results and Discussions  
In the above studies it was shown that on the beginner  
The works of the researchers on the history of the grade  
level younger learners’ curiosity, their direct interest to the  
surrounding as well as desire to perform socially important  
jobs determine their positive attitude to studies and,  
consequently, their emotional experience regarding  
assessment (17). That is why student lag, bad marks can often  
hurt feelings, even drive students of this age to tears.  
Moreover, primary school students lay special emphasis on  
their intellectual abilities and on how they are evaluated by  
other people (26). And what is more, the children of this age  
group are longing for acknowledgement; it’s highly important  
for them that a good mark should be recognized and approved  
by all (18).  
The study of the peculiarities was conducted with the  
method of child adapted by E.M. Alexandrovskaya and I.N.  
Gilyasheva (1) 12 FLO-120 and teenage form 14 PF variant  
of person’s questionnaire child and teenage versions. As the  
given variants differ in number of the scales and age  
standards, we made up our minds to remain only those scales  
which were presented in both versions without running a raw  
score analysis but by using wall values. The study of anxiety  
was made through the method of A.M. Prokhizhan “The scale  
of a personal anxiety”. The results of the correlation analysis  
with the use of non-parametric criterion made up by Spirmen  
(
4) show that despite some attempts to abolish the mark  
system to assess knowledge, in Russian Pedagogy a more  
precise, reasonable and adequate way to evaluate results of  
students’ work hasn’t been found yet. At present, the school  
mark is not only a measure of learning school programs, but  
also it has a great impact on the emotional sphere of a child at  
school, as well as his self-estimation (23, 31, 33).  
There comes a logical question: to what extent does the  
system of assessment affect modern children and how  
important is it for students to develop the ability to estimate  
acquired knowledge and understand the school grade as a  
result indicator of their learning activity? (12). The analysis  
of psychology-pedagogy literature and my own experience  
proves, without controversy, the existence of a close relation  
between successes achieved in learning and formation of a  
learner’s personality (5, 20).  
Nevertheless, each age group is influenced by grades in  
different ways. That’s why the aim of the study is to find out  
the correlation between the attitude of students on different  
educational levels to school grades and their personal  
qualities. We suppose that there is relationship between  
students’ personal features and their attitude to school marks.

Materials and Methods  
In the course of the study the following methods were  
to school marks, their personal features and anxiety level are  
presented in Table 2.  
used: theoretical (analysis; synthesis; concretization;  
generalization); empiric and diagnostic (the use of child  
adapted by E.M. Alexandrovskaya and I.N. Gilyasheva (1) 12  
FLO-120 and teenage form 14 PF variant of person’s  
questionnaire; the test “The scale of person’s anxiety” of  
A.M. Prikhozhan (16) and the modified questionnaire of I.B.  
Umniashova (22) “The grade as learners see it”); methods of  
math statistics. All sample of the research: 180 students  
harmonized by sex (90 males and 90 females) took part in the  
study. All the tested, aged 9-17, study in the same secondary  
school. 60 students are doing in primary school (3-4 classes),  
The situation starts to acquire another turn later, with  
years, in junior school, when personal value of grades is  
growing due to awareness that the mark does not rate a  
student, as an individual but the result of a job he did (15).  
Sh.A. Amonashvili remarked the decline of the status role of  
grades in junior school which is manifested in a formal  
attitude to marks (2). Graduates’ attitude to the school marks  
is basically determined by their professional views (plans).  
Because of this, they begin to see school subjects from the  
view point of their future profession and consequently, they  
start to differentiate marks they have. If they get a bad mark  
in a subject which is out of their professional interests, the  
attitude to them will be quieter than in necessary disciplines  
(5). Based on the data in Table 2 we may come to conclusion  
stating that between the attitude to the grade, psychological  
qualities and anxiety level there are authentic correlations.  
The answers to question 2 “Do you find your marks  
unfair?” and the index “Anxiety and big concern” - scale O  
(r=0,384; p≤0,05). To our minds it may point to the fact that  
learners are rather inclined to see unfavorable sides of  
assessment, a small involvement of a teacher in the process,  
his\her subjectivity. The aim of assessment should be the  
formation of feedback between the student and the teacher,  
possibility to motivate learners, develop such qualities as  
desire to learn, the ability to self-improve, analise and  
estimate their own performance, encourage cognitive activity  
(21).  
6
0 are on the middle stage (8-9classes) and 60 are high  
school students (10-11 classes). To study the peculiarities of  
attitude of the pupils from different classes to grades we used  
the modified version of the questionnaire “The mark as  
school learners see it” worked out by I.B. Umniashova (22).  
The results of the questioning “The mark as school learners  
see it” are presented in table 1.  
The analysis of the results given in table 1, states that  
school students’ attitude to the grade is different in different  
groups. Practically all the testees admitted that a school grade  
is necessary for assessing knowledge. In most cases they  
agree with the given marks, and a negative result (a bad  
grade) can be explained by their insufficient homework (14).  
Besides, on each age stage their attitude to school grades is  
changing. For example, primary school students orient  
themselves mostly to their parents’ or teachers’ opinions,

The answers to question 4 “What do you hate  
The received data show that the more the process of  
assessing acquires personal significance for learners, the less  
interpersonal anxiety they have to endure, as they stop to be  
dependent on outer circumstances while being assessed and  
can rely on their own efforts to receive a desired positive  
assessment. Such attitude to assessing process leads to  
reduction of formation of the qualities  independence, self-  
confidence, carelessness.  
Thus, based on the conducted correlation analysis we can  
safely conclude that there exist considerable relationships  
between attitude of students of different age stages to the  
school grade, learners’ personal anxiety level as well as some  
personal features of theirs.  
when you get a bad mark?” and the following indexes school  
anxiety (r=0,606; p ≤0,01) and the personal features “good  
faith and diligence” – scale G (r =0,395; p≤0,05). The data  
testify the fact that the more the students fear poor grades and  
punishment for them, the more they get frustrated and  
anxious. Though, it should be mentioned, in this case the  
features “good faith and diligence” are growing as children  
tend to do their best to avoid censure. Many researchers  
remark that some students are often afraid to fall short of  
people’s expectations; they may feel anxious about self-  
expressing or before their teacher (9). The biggest fear at  
school is fear of a situation before control works (7). If a  
student constantly gets a poor mark, the experienced failure  
leads to the lost of self-confidence and due to this, a low level  
of claims is growing. The chain of the consequences may end  
with forming negative attitude to study and the desire to learn  
is vanishing (10).  
4 Conclusions  
The conducted research of the psychological features of  
student’ attitude to the school grade allows us to make  
conclusion about the necessity of a great attention of school  
teachers to the problem of assessing. There are three urgent  
questions to be solved: -How should learning be evaluated at  
school? - What kind of assessment must it be?  What place  
must the grade take in the system of education?  
The results of correlation analysis, given in table 2 allows  
us to reveal the negative correlations between:

The answers to question 1 of the questionnaire  
Why is the school grade necessary?” and the following  
indexes: interpersonal anxiety (r=-0,648; p≤0,01), general  
anxiety level (r=-0,302; p≤0,05), and also such personal  
features as “openness, good will” - scale A (r=-0,464;  
p<_0,01), “self-confidence, stability” –scale C (r=-0,581;  
p≤0,01), “Dominating, independent” – scale E (r=-0,518;  
p≤0,01), “Tend to be risky, careless” – scale F (r=-0,539;  
p≤0,01). The data may point to the fact that if students see a  
mark as a variant of an indicator of their knowledge, the  
interpersonal and general anxiety levels decrease. This  
phenomenon might be connected with the assurance  if they  
get enough knowledge, they will have a good grade  thus,  
there is no reason to worry, no one can condemn or criticize  
and their personal relationships will not go bad. Though,  
attitude to assessment at school as a determination of  
knowledge does not welcome the formation of openness,  
stability, independence and carelessness, because it involves  
We consider it sensible to refuse the traditional practice  
of assessing when the function of the grade is assigned to  
teachers and psychologists. The student should get involved  
in the process. Only then we will be able to form valuation  
activity of learners and develop objective self- assessment of  
the results. Such objective self-assessment must take into  
consideration the previous child’s achievements and it must  
be based on them. A student should learn to compare “what I  
could” and “what I achieved”, “how I have changed making  
progress”. It’s the result of a change that ought to be the basis
