Yup... I said it. Given all the buzz from that McCleod & Crowe article last year, it should be no secret that we've totally been misinterpreting those articulation norms. But, for a lot of SLPs it still begs the question... "then at what age should we be addressing particular sounds in speech therapy?"
Some of the most common questions I hear from SLPs sound something like this:
"When should I start treating kids for /r/ errors?"
... or ...
"Aren't /s/ sound errors still age appropriate for preschoolers?"
Those are the WRONG QUESTIONS.
If we base eligibility criteria and/or target selection primarily on arbitrary "cut-off" ages for acquisition of sounds, then we're missing the whole point. There are so many other variables that should be considered in addition to what particular sounds a child has at a particular age...
I like a good bar graph as much as the next guy... but I have to remind myself its just one piece of a bigger puzzle.
Let's take the /s/ sound, for example. Here are some factors I take into consideration when I decide whether or not to recommend speech therapy:
Now, I completely understand that many school-based SLPs are all too often bound by black-and-white eligibility guidelines put in place by administrators with little to no understanding of the nuances of SSDs. And believe me, I can totally empathize with the concerns over gigantic caseloads in light of all these considerations (I was a school-based SLP for many years, myself). Unfortunately, I have no easy answers. I just know that we do our kids and their families a disservice when we solely rely on speech acquisition norms as an arbitrary threshold for eligibility criteria.
With everything we’re learning about complexity theory, how we’ve been misinterpreting those speech acquisition charts, and how speech delays/disorders can impact literacy... it becomes pretty clear that there really is no “magic age” at which we should begin providing intervention for kids with errors of particular sounds. It’s much more complicated than that.
There is so much confusion among parents and professionals about who is most qualified to give a definitive diagnosis of Childhood Apraxia of Speech (CAS). To understand who should be diagnosing this disorder we have to understand what CAS actually is...
"CAS is a neurological childhood speech sound disorder in which the precision and consistency of movements underlying speech are impaired in the absence of neuromuscular deficits (e.g., abnormal reflexes, abnormal tone)..." Ad Hoc Committee on Apraxia of Speech in Children, American Speech-Language-Hearing Association, 2007
There are 2 important aspects of this definition... one usually leads to confusion about who should diagnose, and the other actually helps to clarify the confusion.
1. "neurological"... That word understandably leads many people think that a medical professional (specifically a neurologist or developmental pediatrician) would be most qualified to give a diagnosis. But, as Cari Ebert, an SLP and nationally recognized speaker on the topic of CAS has explained, it simply means that the issues with the child's speech difficulties begin in the brain, not the mouth.
This word also leads people to believe there are usually medical tests (e.g., MRI) that can reveal the cause of CAS. Though CAS can occur with other neurologic impairments (childhood stroke, infection, trauma, etc.) that do yield positive findings on imaging studies (i.e., MRI), this is usually not the case as CAS is very often idiopathic (unknown cause). "Imaging and other studies have not been able to find evidence of brain damage or differences in the brain structure of children with Apraxia of Speech." Apraxia of Speech. National Institute on Deafness and Other Communication Disorders (NIDCD). Accessed 1/4/2016.
2. 'speech sound disorder"... this phrase provides the clarification we need! CAS is at it's core a SPEECH disorder. And who is the most qualified professional to diagnose speech disorders?... speech language pathologists (SLPs)! In fact, the word "pathologist" by definition refers to the SLPs ability to actually diagnose speech and/or language disorders. Although consulting neurologists, developmental pediatricians, psychologists, etc. can be helpful and sometimes necessary, these professionals do not have the education, training or expertise to differentially diagnose CAS from other speech/language disorders or delays.
Does this mean that all SLPs are qualified to diagnose CAS? NO and here's why...
CAS is a very rare condition. It occurs in 1-2 children per 1,000 (Shriberg et al., 1997) and is found in only between 3-5% of children with speech disorders (Delaney & Kent, 2004). That means that most SLPs won't see very many children with CAS across their entire careers so we can't expect all SLPs to have expertise in diagnosing a disorder they rarely come across.
So, is it really all that crucial to find an SLP with expertise in CAS to make sure you have an accurate diagnosis? Yes! A particular diagnosis informs the type of therapy a child receives. It is imperative that the speech therapy approach is matched to the nature of the child’s speech disorder and misdiagnosis can prevent children from receiving the help that they really need to progress.
I often hear from parents living in countries outside the U.S. that MDs are the ones that provide the "official" diagnosis or that insurance companies require that the diagnosis come from an MD. But, please remember if an MD gives your child a CAS diagnosis without the input of an SLP who has conducted a thorough motor speech assessment, you may not have an accurate diagnosis. And a thorough motor speech assessment can only be conducted with children who are verbal. So, although we can "suspect" that a non-verbal child may have CAS and treat accordingly, a definitive diagnosis should never be made in this instance.
So how do you know if your child has an accurate diagnosis? Here are some questions to ask the professional who diagnosed your child....
Lastly, here are 2 ways to make sure you're getting the best information and services for your child:

Nothing strikes more fear in the heart of an SLP than those two little words... lateral lisp. To most parents it seems like an easy fix. It's just a sound or two that their child has trouble with... a few speech therapy sessions and boom, it should be fixed, right? Nope! Not that simple.
Now if you're NOT a speech language pathologist, let me first define some terms. Primarily speaking, there are frontal lisps and there are lateral lisps.
A frontal lisp occurs when the tongue either protrudes between, or touches, the front teeth and the sound produced is more like a /th/ sound than a /s/ or /z/. Many children go through a perfectly normal phase of producing a frontal lisp. Most will outgrow this and will be able to produce a correct /s/ sound by around kindergarten. Children who continue with a lisp past this age typically require speech therapy to correct it.
A lateral lisp occurs when the air escapes over the sides of the tongue and into the cheeks.... this can occur on several sounds, /s/, /z/, /sh/, /ch/ /zh/, and /dj/. Parents of children with lateral lisps often describe their child's speech as sounding "mushy" or "garbled". These types of lisps are NOT developmental. Children with lateral lisps do not typically outgrow it and will require speech therapy to correct.
Now speaking to my SLP colleagues.... if you have a child with a lateral lisp I'm assuming you've done a thorough oral motor/mechanism exam to determine if the child has any structural or functional issues. If not... do it! There are often myofunctional issues with these kids and those should be addressed (that's a post for another day).
Let's talk about speech therapy for a lateral lisp....
The first thing we have to do is elicit the correct production of the target sound, whether /s/, /sh/, or /ch/ (I always start by targeting voiceless phonemes). Essentially, these kids have to learn to anchor the lateral borders of their tongue to the interior margins of their molars to prevent air from escaping laterally. There are so many wonderful techniques to cue correct tongue placement, such as the butterfly technique, using straws, and fantastic resources from Pam Marshalla.
For /s/, I probably don't do anything much different from the above techniques, but I call it the "long /t/ sound". It looks like this...
BUT THAT'S NOT THE SECRET!
If your clients are anything like mine they quickly figure out that I'm trying to get them to say /s/! Ugh... which. means they automatically go right back to that lateral airflow when we move to the word level. Oh, the frustration!
So, here's my "secret" (drum roll please)...
Tell the child you're NOT going to work on the /s/ sound! That's right.... you're done with /s/ and aren't even going to talk about it anymore! You are going to create a completely new sound! This mental shift has been key to my clients creating a new motor plan for correct production of /s/. The child gets to name this "new sound" and even create its very own symbol.
Once they have mastered this "new sound" in isolation (using any of those techniques above) we move to adding it to words with /t/ in final position (cat, bat, hat) and I have them draw their symbol for this "new sound" at the end of the word. Sometimes, at this point they begin to realize we're really working on /s/ and begin to lateralize again... I remind them, NO /s/ sounds! Only use the "new sound". Then we start "removing" the /s/ sound from words and "replacing" it with the new sound. Now once the lateralization has been eliminated for a good period of time, of course we inform them that this new way is actually how we should be saying /s/, which comes automatically most of the time.
***A word about carryover... Don't forget to use those principles of motor learning to promote generalization of these skills. Working through a hierarchy of constant to variable positions in words/phrases, blocked to randomized practice, and simple to complex tasks will ensure your kids with articulation deficits won't be in years of speech therapy without significant progress.***
Well, there it is... my big secret for correcting a lateral lisp. Nothing fancy, but it works!
