I believe points are assigned the same for all ages but suspension occurs at a lower level based on age.

6. Point System.
I. Point Accumulation. A driver's license is subject to suspension if they accumulate either 12 points within 12 consecutive months or 18 points with 24 consecutive months. For provisional drivers, suspension would occur if they accumulate either 9 points within 12 consecutive months, 12 points within any 24 consecutive months or 14 points from the time the provisional license was issued. In the case of minor drivers, suspension would occur if they accumulate either 5 points within 12 consecutive months or 6 points from the time the license was issued. For chauffeurs, suspension would occur if they accumulate (while in the course of employment) either 16 points in 1 year, 24 points in 2 years or 28 points in 4 years. §42-2-127(1)(a)

II. Point Schedule. The following points are assigned for speeding violations. Three (3) points for going 5 to 9 MPH over either the reasonable and prudent speed or the 75 MPH maximum limit. Four (4) points for going 10 to 19 MPH over either the reasonable and prudent speed or the 75 MPH maximum limit. Six (6) points for going 20 MPH or more over either the reasonable and prudent speed or the 75 MPH maximum limit. Three (3) points are assessed for a failure to reduce speed when a special hazard exists. And, 3 points are assessed for other moving violations. No points are assessed for going 1 to 4 MPH over either the reasonable and prudent speed or the 75 MPH maximum limit. §42-2-127(5)(f) & (r) Important. No points can be assessed against a person's driving record if the original citation was issued via an "automated vehicle identification system." §§42-2-127(5.5) & 42-4-110.4(3)
