The 14-year-old Victoria College student has already already attended his first training camp with the county and he will be having a second coaching weekend in Jersey this weekend at the Langford Sports Centre.
Jenner, a wicketkeeper and batsman, will receive individual coaching with Sussex’s professional coaches in both Jersey and at the Probiz County Ground in Hove.
The teenager will be part of Sussex’s under-14 age group squad next summer before moving on to the U15s in 2013.
