There are two issues with your code:

  1. You compare things using ==, in your code you use a single = sign, which is incorrect as that is used to assign values, not compare them.

  2. String values (text values essentially) have to be wrapped in quote marks, you can't just type them out, doing that will make JavaScript think you are referencing a variable or something along those lines.

Fixing those two issues produces this code:

var isAdmin = true;
var isStudent = false;

if (isAdmin==true) {
alert("Welcome administrator")
}

Which will pass the challenge.
