Speech-Language Milestones Resource List

Updated: Jun 4, 2022

*If using a mobile device, switch to desktop view of this page to improve display*

For the longest time, I've been meaning to print a bunch of milestones resources, sort them by speech-language skill area, and organize them in a binder (#unrealisticgoals). Since that hasn't happened yet (I blame 2020 and the shortage of HP printer ink), I decided to put them all together in one blog post.

Note: the vast majority of these resources were originally compiled in the SLPs for Evidence Based Practice Facebook group by Tatyana Elleseff, group admin, under the Giant Milestones post, which can be found here. Thank you, Tatyana!! I have found myself returning to the group page and searching for the milestones post more times than I can count, so I thought having them all together on one page with downloadable PDFs might be helpful to other SLPs who have been doing that repeat search too.

If there is anything I'm missing that you think should be included, please feel reach to reach out using the contact form at the bottom of my site or DM me on Instagram (@spiffyspeech).

Development of Figurative Language - Excerpt from Figurative Language: Assessment Strategies and Implications for Intervention by Bernstein, D.K., 1987

"The developmental studies of metaphoric comprehension reveal that metaphoric ability is present even in preschoolers and that metaphoric language comprehension increases with age... Perceptual metaphors are comprehended more easily than psychological ones and that predicative metaphors (being cognitively simpler) are more easily understood than proportional ones... Research to date reveals that the literal meaning of idioms is understood before its nonliteral meaning. Furthermore, it appears that idioms are processed as ‘chunks’ and that their comprehension is aided by a variety of linguistic and paralinguistic cues...Comprehension of idioms begins to develop in the early school years and continues to grow through adolescence...Finally, children’s ability to understand idioms seems to depend on four factors: the frequency of their exposure to idioms: the relevance of idioms to children’s experiences; the linguistic context in which idioms are set; and the mode or task used to test idioms...Developmental studies of proverb comprehension seem to indicate that the understanding of proverbs emerges at about age 7 and that the comprehension of proverbs steadily improves through childhood and adolescence. It also appears that proverbs are more difficult to understand than metaphors and idioms...This may be due to the fact that some proverbs contain uncommon syntax. "
