The purpose of present study is to understand whether there are any significant differences rental attitude between the parents of high-achieving and under-achieving junior high school students. Roe and Siegelman´s Parent-child Relations Questionnaire (PCR) has been used as the instrument to measure the parental attitudes through the perception of students. The results shown, the differences of responses of between high-achieving and under-achieving students reach the level of significance on five out of the ten scales of PCR. They are loving, neglecting, rejecting, symbolic-love reward and symbolic-love punishment. Generally speaking, the high-achieving students have perceived their parents as showing more love and regard toward them and using symbolic-love reward more often in their child-rearing practices. On the contrarary, the under-achieving students have perceived their parents as being more neglecting and rejecting, using symbolic-love reward less often but using symbolic-love punishment more often. There have been no differences of responses between the high-achieving and under-achieving students on the scales of protecting, demanding, casual, physical reward and physical punishment. There are significant differences in responses between sex, boys have perceived their parents as being more demanding, using both rewand and punishment more often in their childrearing practices than girls. Girls are more likely to perceive their parents as showing more love and care toward them than boys. The subjects´ responses toward father-child relations questionnaire and mother-child relations questionnaire are basically the same except that mothers have been perceived as being more rejecting than the fathers.
