The answer I have given applies to kids in primary school or "elementary" as americans call it. There are two types of english tests
Spelling: 1.give every pupil in the class some paper 2.say some english words e.g "Write down the spelling for Tree" 3.the pupils write down the words that you ask them to spell and you just mark them at the end simple.
And finally Writing:
1.Give every pupil in the class some paper 2.Ask them to write down something for example: A story about a holiday or their favourite thing in the world. 3.Give them as much time as they need and then read through the papers later and give marks for being interesting.
