We must understand phonological processes first to fully understand phonological disorders.
So what are theses processes? They are the natural way children simplify language as they learn to speak. Speaking like an adult takes quite a bit of coordination of our tongue, lips, and vocal tract. Therefore, as children learn to speak they will naturally simplify words to make it easier. These processes are normal and expected!
For example, one common process is called "final consonant deletion." A child who uses this process will delete the last syllable of multi-syllabic words. He or she may say "wa" for "water." This is normal and usually disappears by 3 years of age.
Phonological disorders occur when the processes persist past the age when they are suppose to disappear. The link below takes you to a chart of common processes and the age when they are supposed to disappear.

Therapy for a phonological disorder will look a lot like articulation therapy to a non-speech pathologist. Your child will work on the pronunciation of sounds within words and sentences. However, your child will work on the persisting processes instead of specific sounds
For example, your child may be demonstrating a process called "fronting." This means that your child may be moving all of his or her back sounds (/g/ or /k/) to the front of their mouth. Your child may say "doal" for "goal." During therapy, your child will work on bringing those "back" sounds to the "back."
Articulation disorders and phonological disorders are very similar. Therefore, they are often confused and misdiagnosed. Some key characteristics of phonological disorders include:
