Hello,
Writing a placement test from scratch is extremely difficult, as it requires extensive experience in English language and knowledge of statistics to create a timed test that effectively measures students' proficiency. Additionally, you should administer the test to at least 30 students to evaluate the exam's effectiveness before applying it to all students. This stage is called a "pilot study."
But prior to that, you also need to have English language teaching experts (at least five ) to review the test you designed for "face validity" In statistics , this means that experts examine ( review) the questions and make necessary amendments to ensure they align with students’ proficiency levels, age, and measure subject matter. Furthermore, it is essential to consult a statistics expert both during and after the test design process.
Assessing writing is subjective and requires extensive experience. Writing is a skill that depends highly on grammar and vocabulary knowledge, both of which mean that students with a strong command of grammar and vocabulary are more likely to perform well in writing.
I have attached a placement test - a 60-question exam designed by Oxford University which provides insight into your students' proficiency level and helps determine the appropriate writing textbook to start with. After you calculate the scoring, the recommended books given at the end is measured according to European Framework of Reference for Languages. For example, "12 or below: If the candidate’s score is 12 or below, then he or she should use Business Result Elementary" (A1 textbooks) and so on.
PS. There are many better placement tests you can find and might serve you better than what I have attached.
After administering the exam, calculate the scores accordingly "at the end of the attached file" It is truly a tough process. The million-dollar question is "Do you really need to do all that?"
I think I also have placement tests for vocabulary and writing. I will check my computer and get back to you. Good luck
