BSCI驗廠審核有效性如下：

　　A 或 B 級：

　　除非需要進行跟進審核，正常情況下BSCI 全面審核在2年內有效。在這種情況下，工廠的總評級是A或B級。

　　凡被評為A和B級的工廠都有機會在兩次全面審核期間接受突擊抽查。

　　Rating A or B:

　　BSCI full audits are valid for 2 years, unless follow-up audits are to be conducted. This is the case for factories that receive an overall rating of A or B.

　　Factories rated A and B are eligible to receive a Random Unannounced Check in the period between the two full audits.

　　C、D 或 E 級：

　　當工廠在全面審核后收到總評級為C、D或E時，工廠需要在60天內在平臺上提交改善計劃（依照下頁的操作指引），該審核在進行跟進審核前有效。

　　跟進審核應按照改善計劃規定的日期執行，但僅在最近的審核后的12個月內進行：

　　若跟進審核結果表明有改進（例如獲評A或B 級），最新的審核結果將保持有效至原全審到期日為止。

　　若跟進審核結果是 C、D 或E級，該跟進審核結果有效期到下一次跟進審核期為止。

　　Rating C, D or E:

　　When a factory receives an overall rating of C, D or E after a full audit, the factory has to submit improvement plan through the platform (According to operation guidance of following page), this audit is valid until the follow-up audit is conducted.

　　The follow-up audit shall be conducted on the date defined in the Remediation Plan but it can only take place up to a maximum of 12 months after the last audit:

　　If the result of the follow-up audit shows improvements (A or B rating) then the audit is valid until the full audit is due。
