The purpose of the present study was to fit polynomial to the individual longitudinal height data and examine the latent characteristics of individual's height growth in the term over 6 and 20 years old in girls. The longitudinal height growth data were collected retrospectively from 45 subjects, who were senior student of a certain women's junior college in 1991. In Thirty-five of individuals, their height growth data could be described by 10th to 12thdegree polynomials, and averages of their mean squared residuals and of their mean relative residuals were 0.1512cm2 and 0.0716%, respectively. It could be recognized that the polynomial could describe the individual longitudinal height growth distance data and the mathematical characteristics of the determined polynomial for each individual can give the information regarding the own's latent growth characteristics. Another height growth acceleration was found in 11 of individuals after their Peak Height Velocity. It was suggested whether such another growth spurt appears must be studied further and proved.
