求翻译：The quality and validity of any assessment tool is confirmed by reviewing, trialling and modifying the tool. You should get relevant people to review your assessment tools. You can then trial them on a sample target audience to identify potential problems and areas for improvement. From the review and trial, you will identify any changes that need to be made.是什么意思？
