It means that the candidates' scores in the senior high school entrance examination have not reached the minimum admission score for taking the senior high school entrance examination. The senior high school entrance examination refers to the unified admission method for high school enrollment, which is usually organized and implemented by the education department or relevant institutions to provide candidates with fair and just admission opportunities. The joint recruitment line refers to the lowest score line for high school admission, and only candidates who meet or exceed this score line are eligible to participate in high school admission. Therefore, if the candidates' scores in the senior high school entrance examination don't reach the entrance examination line, it means that they can't participate in high school admission and need to choose other ways to continue their studies.
