Although today the Young Artist Association has strict age requirements regarding which nominees are eligible for a Young Artist Award nomination , the association did not originally have such specific age restrictions . Today , candidates eligible for a Young Artist Award nomination must be between the ages of 5 and 21 at the time of principal production of the project for which they are nominated . However , the eldest winner of the " Best Young Actress in a Feature Film " award is Lea Thompson , who was 26 years old the night she won for her performance in '' Some Kind of Wonderful '' at the 9th Youth in Film Awards ceremony ( 1987 ) . The youngest winner of a " Best Leading Young Actress in a Feature Film " award is Robin Weisman , who was 6 years old the night she won for her performance in '' Three Men and a Little Lady '' at the 12th Youth in Film Awards ceremony ( 1990 )
