Wrong: Many changes are occuring at every level of education.
Right: Many changes are occurring at every level of education. The reason why the "r" is doubled in the -ed and -ing forms is that the stress falls on the final syllable of the verb in its infinitive form: occur. The same rule applies to most other verbs ending in -ur and -er where the stress falls on the final syllable: prefer → preferred → preferring confer → conferred → conferring concur → concurred → concurring When the stress does not fall on the final syllable, the -ed and -ing forms are spelled with one "r":
utter → uttered → uttering
cater → catered → catering
murmur → murmured → murmuring
