Hubei's "three supports and one support" exam has a high pass rate. Because Hubei's "Three Supports and One Support" plan recruits grass-roots staff, and the demand for grass-roots staff in Hubei is relatively large, Hubei's "Three Supports and One Support" plan has received extensive attention and support in this respect, and the corresponding examination training and preparation resources are also relatively rich, and the passing rate of candidates is also relatively high. The demand for grass-roots work in other areas is relatively small, the attention and the number of applicants of the "three supports and one support" plan are relatively low, and the candidates' preparation resources may not be sufficient in Hubei, so the pass rate is relatively low. In addition, the difficulty of the test and the design of the test questions are also factors that affect the passing rate. To sum up, there is a reason for the high pass rate of the three-support and one-support examination in Hubei.
