When you take a look at your kid's school work that has been marked you might notice a huge variety of codes written at different points on the page. It can be a tricky task working out what all these mean and you may have no idea if it suggests your kid is succeeding or failing.
However, one TikToker has thankfully answered all your prayers as she has unveiled many of these tricky acronyms once and for all so that you can be sure what the teacher is trying to say the next time you look over their school work.
TikTok user Miss Frankie often shares clips of her life as a teacher but a recent video of hers has gone viral after copping nearly 190,000 likes.
The video shows her sat next to her non-teacher friend and Miss Frankie said: "Ok, I'm a Primary teacher and Zoe is a midwife.
"So I'm going to ask her what some of these acronyms mean that I use in work. Starting off easy, so what does LO stand for?."
Widow brings pillow with late husband's face on it to pub every New Year's EveZoe immediately responds with the correct answer, Learning Objectives.
The primary teacher then rattles through some much harder acronyms, such as PP/FSM which Zoe is not able to guess correctly. The answer is People Premium/Free School meals.
Following this, Miss Frankie asks one which most of us might already know, EBI and WWW. Zoe correctly identifies these as Even Better If and What Went Well to highlight where improvements could be made in a child's piece of work.
The teacher then continues to ask for the answers to acronyms which grow in difficulty. After one of these more tricky ones, Zoe claims: "This is the hardest one."
She was asked to identify the meaning of KCSIE. After being stumped for a while she hazards a guess that it has something to do with checking on kid's progress throughout the year.
However, the answer is far more simple and actually the most important one as the answer is Keeping Children Safe in Education.
When she finds out the answer, it all makes sense to Zoe.
In response, many commented that they should play the reverse game and test the teacher's knowledge of midwifery terms as one wrote: "Now do it the other way round. Do you know many midwife acronyms?"
While another said: "Do the opposite now! As a midwife I want to see."
