This paper proposes a new attitude scale of the creativity in mathematics learning. I call this attitude scale as CAS (Creative Attitude Scale). I analyzed factors on the creativity which are known so far. The attitude scale was composed of 7 factors consisting 27 items. On composing the scale, I investigated the degree of discrimination for each item, the reliability of all the items, the correlation coefficient between each item and the correlation coefficient between CAS and the scales which were proposed by Torrance, E.P. and Munzert, A.W. The results of experiments performed on 753 students of elementary school (grade 6) and junior high school (grade 1-3) are as follows: ・The degree of discrimination for each item is very high. ・ The value of coefficient a' of reliability of all the items is 0.97. ・The value of correlation coefficient between each item ranges from 0.40 to 0.75. ・The values of correlation coefficient between CAS and the attitude scales which were proposed by Torrance, E.P. and Munzert, A.W., range from 0.88 to 0.92. These results show a higher discrimination and larger reliability of CAS. Suggesting that it is a suitable scale which measures attitudes of creativity. Also, I classified the values of the measurement by CAS in five steps and interpreted the creativity for each step.
