Question

When we say PE, are dots a must?
Do we need to write as 'P.E.'?

Thank you!

Answer

No, you don't. It's fine without the dots.

Answer

No, you don't have to, but you may. Both PE and P.E. are understood and accepted usage. "Phys Ed" is also a common abbreviation.

Answer

In both British and American English, if you are using initial (i.e. first) letters to represent words, you don’t normally need to put a full stop after them. Example BBC, UK, NATO

In American English, it is common to use a full stop as an alternative style for certain** abbreviations. Example USA and U.S.A. both are right abbreviation for "United State of America"

PE is abbreviation of Physical Education. 
PE is more formal and correct without dots(.)

Answer

Yes, there is a name called abbreviation.
