Familial short stature is indicative when one or both parents are of a short stature, and the height and weight percentiles are under the 5 percentile threshold. [7] The child will be concordant with the mean parental height, and the bone age should be normal. Constitutional growth delays are marked by low height and weight percentiles as early ...
Children with failure to thrive usually have a weight that is below the 3rd or 5th percentile for their age and a declining growth velocity (meaning they are not gaining weight as expected). Recently it has come to light that current growth charts for infants under 24 months overstate the expected weight of babies and lead to potentially obese ...

The diagnosis of FTT relies on plotting the child's height and weight on a validated growth chart, such as the World Health Organization (WHO) growth charts [62] for children younger than two years old or the U.S. Centers for Disease Control and Prevention (CDC) growth charts [63] for patients between the ages of two and twenty years old.

The 25th percentile is also known as the first quartile (Q 1), the 50th percentile as the median or second quartile (Q 2), and the 75th percentile as the third quartile (Q 3). For example, the 50th percentile (median) is the score below (or at or below , depending on the definition) which 50% of the scores in the distribution are found.
Upon recollection of data from MGRS, in 2007, the World Health Organization (WHO) launched gender specific height-for-age and BMI-for-age charts for 5- to 19-year-olds (upper limit of adolescence as defined by WHO). [2]
The Tanner scale (also known as the Tanner stages or sexual maturity rating (SMR)) is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics , such as the size of the breasts ...
In educational statistics, a normal curve equivalent (NCE), developed for the United States Department of Education by the RMC Research Corporation, [1] is a way of normalizing scores received on a test into a 0-100 scale similar to a percentile rank, but preserving the valuable equal-interval properties of a z-score.
