Semi-quantum secret sharing is an important research issue in quantum cryptography. In this paper, we propose a ( t , n ) threshold semi-quantum protocol, which combines the practicality of protocols and flexibility protocols. Participants prepare transmit single particles circular way, then any out participants can recover according to Shamir’s scheme. As resources, are easy prepare. Furthermore, classical only need possess capability insert particles. The security analysis shows our protocol has against most attacks. Except decoy particles, all useful carry message, so efficiency proposed achieve 100%.
