Mean Scale Score for CSTs. This is the arithmetic mean or average of the scale scores for all students who took each grade-and/or content-specific CST without modifications. The scale scores for each grade and subject area range between 150 (low) to 600 (high).
Causes of central precocious puberty can include: 1  damage to the inhibitory system of the brain (due to infection, trauma, or irradiation), 2  hypothalamic hamartoma produces pulsatile gonadotropin-releasing hormone (GnRH), 3  Langerhans cell histiocytosis, or.  McCuneâAlbright syndrome.
It may seem like kids are growing up faster these days. But central precocious puberty (CPP) is a rare condition. It happens when the body matures sooner -- perhaps years earlier -- than expected. Puberty usually starts around age 7 1/2 in girls and around age 9 in boys. For some children, such as those who are African-American or Hispanic, normal puberty may happen as early as age 6 in girls and age 8 in boys. But with CPP, signs of puberty, such as budding breasts and body hair, show up much sooner than parents might anticipate. It's more common for girls. When it does happen in boys, there's a good chance there's an underlying, potentially serious medical cause that needs to be treated.
