I have a problem with comma use in the following example: “They determines the goals, objectives, and wrote the school's improvement plan.”
Your problem is verb tense and faulty parallel structure, not comma use:
"determines" should be in past tense in order to agree with "wrote."
"determined the goals" and "wrote the school's improvement plan" are not parallel in structure with "objectives." You can lump "objectives" in with "goals" or give it its own verb:
"They determined the goals, identified objectives, and wrote the school's improvement plan."
"They determined the goals and objectives and wrote the school's improvement plan."
