Emerging language can occur beyond early childhood; individuals can have emerging language skills even after early years.
Transitioning to developing language stage, typically encompasses ages from 3 to 5.

By ages 3 to 5:
- Expressive vocabulary can reach approximately 250 to 300 words.
- For receptive vocabulary, it’s estimated to be 900 to 1000 words.
Children progress from 50 words to using two-word phrases and short sentences.
Sentence construction may still lack grammatical accuracy at ages 3-5, leading to simple sentence structures.

MLU tends to be short at initial stages and increases progressively from ages 3 to 5.
By ages 4 and 5, sentences become more grammatically correct and longer, demonstrating developmental advancement.
Typically, children do not use complex language structures comparable to adult sentences at this stage.

The developing language period corresponds to Brown’s stages (detailed in Chapter 8).
These stages are important not only for this course but also for language and literacy-related courses.
It's critical to study these stages, including reading the associated chart and understanding their implications for language development.

There will be specific questions on Brown’s stages in assessments, and recognition of the structure of these stages is essential.
A larger laminated chart created by Miss McConnell is available in the graduate work room for better visual understanding.
Notably, children with severe impairments may still function within these stages.
Chronological age vs. Developmental age:
- Chronological Age: Age based on the calendar.
- Developmental Age: Reflects the stage of development a child is currently at, regardless of their chronological age.
- Example: A 22-year-old client may function at the level of a 15-year-old in terms of development.

Children aged 0-2 years (364 days) are under Part C of IDEA (focus on early intervention).
Children aged 3-5 years fall under Part B of IDEA, transitioning from family-centered to child-centered services.
As children transition to local education agencies (public schools), parental involvement changes from being the central focus to being a partner in setting goals.

Observation:
- Allowed without parental consent; however, formal assessments or interventions require consent.
Failure to obtain consent for assessments can lead to severe consequences, including revocation of professional license.
Documentation:
- Must support the rationale for assessment and intervention plans.

Importance of treating parental concerns seriously, regardless of how unrealistic they may seem from the clinician's perspective.
Clinicians should educate parents on realistic goals while maintaining a supportive rapport to avoid discouragement.
Parents' reports can be a valuable source of information, but they might need guidance to accurately represent their child's abilities.

Formal Assessments vs. Screenings:
- Formal assessments ensure a child’s performance is significantly different from peers based on norms. Screenings help to determine if a child is at risk for language deficits.
Criterion-Referenced Assessment:
- Focus on whether a child can perform specific skills rather than comparing to normative data. Informal conversations aid in providing context for understanding abilities.
Screening measures should be short yet psychometrically reliable, avoiding reliance on potentially flawed standardized tests.

Pay attention to peer interactions and families’ concerns to understand a child’s communication competence in natural settings.
Language Sample Analysis:
- Importance of collecting extensive language samples (ideally three to four hundred words) to assess vocabulary, MLU, and sentence types.

Speech Delay: Refers to delays specifically in spoken language rather than overall language skills.
Phonological Processes: Patterns of sound substitutions or deletions common in developing speech that may indicate a speech sound disorder (SSD).
Independent Analysis: Develops phonetic inventories from speech samples.
Relational Analysis: Identifies patterns and inconsistencies in a child’s speech.

Examples and definitions of phonological processes must be clearly understood, with demonstrations provided, e.g., final consonant deletion, stopping, cluster reduction.

Assess if the child's communication leads to effective interactions, observing their behavior in various settings.
Consider supplementary assessments for comprehension and phonological awareness skills as part of best practice.

Respect family choices regarding therapy duration and frequency, despite professionals’ recommendations. Communication with families should remain supportive and educational.

Emphasize the importance of observing real-world interactions and joint assessments to better understand child development.
Document effectively both the clinician's observations and any interventions that contributed to assessment outcomes.
Continuous education on professional assessment methodologies and refining of assessment practices is essential for professional development.
