The researchers conducted the scientific coefficients of two questionnaire forms on sample consists of (20 person) of the research sample and outside the sample. The agreement coefficient between each sentence and its total dimension was used to calculate the two forms credibility. The calculated "R" value of time management ranged between (0.51, 0.95) which is bigger than its tubular value at level (0.05), which confirms the sentences credibility. The calculated "R" value of best scientific methods of time management ranged between (0.72, 0.99) which is bigger than its tubular value at (0.05) which shows the sentences credibility, Then the researcher used Test – Re – Test method to find the two forms stability. It showed also that there is a statically significant correlation between first and second applications for questionnaire sentences of time management where the calculated "R" value ranged between (0.96: 0.99) which is bigger than its tubular value at level (0.05) which the questionnaire stability. Also there is a statically significant correlation between first and second applications for questionnaire sentences of best scientific methods of time management where the calculated "R" value ranged between (0.86 : 0.97) which is bigger than its tubular value at level (0.05) which signify the questionnaire stability. Then put the two last questionnaire forms, attachment (6,7), and a tri-estimate scale of questionnaire sentences have been put, " agree (5), "a little agree" (3) , and " disagree" (1).
