[2] By starting the child ahead, many of the problems associated with grade skipping, such as leaving friends behind or knowledge gaps, are avoided.
[3] Other key factors to a successful grade skip include the desire of the student and the receptivity of the receiving teacher.
These conditions can include: Grade skipping is one of the most cost-effective ways of addressing the needs of a profoundly gifted student[citation needed], as it requires no extra resources[5] and little more than assigning the child to a different classroom, without the expense of special materials, tutoring, or separate programs.
The cost of educating the gifted child in a regular classroom with typical same-age peers is the same as the cost of educating that child in a regular classroom with typical somewhat older students, so grade skipping is essentially cost-free to the school.
[2] Similar to what happens to students who change schools due to moving to a new home, spending less time with former classmates may disrupt some social ties, and there may be a period of stress while the students integrate into their new classes.
