Developmental milestones

Skills and behaviors most children can do by a certain age range, such as walking, using words, or sharing. Teachers use them to gauge whether a child's growth is typical or needs closer attention.

Related: Developmental domains, Atypical development
Developmental domains

The broad areas of growth used to organize child development: physical, cognitive, language, social, and emotional. Observing across domains gives a fuller picture than looking at one area alone.

Related: Developmental milestones, Whole child approach
Atypical development

A pattern of growth that differs noticeably from typical expectations in timing or sequence, such as late talking or unusual motor patterns. It signals a need for observation, screening, or referral rather than a diagnosis by the teacher.

Related: Developmental milestones, Developmental screening
Object permanence

The understanding that objects and people continue to exist even when out of sight. It typically emerges in infancy and underlies peekaboo games and early separation distress.

Related: Sensorimotor stage, Separation anxiety
Sensorimotor stage

Piaget's first stage of cognitive development, roughly birth to age two, when infants learn through senses and actions. Understanding develops through touching, mouthing, reaching, and experimenting with objects.

Related: Object permanence, Preoperational stage
Preoperational stage

Piaget's stage from about ages two to seven, marked by symbolic play and language growth but limited logic. Children often think egocentrically and focus on one visible feature at a time.

Related: Egocentrism, Conservation
Egocentrism

The young child's tendency to see the world only from their own viewpoint and to assume others share their knowledge and feelings. It fades gradually with social experience and maturation.

Related: Preoperational stage, Theory of mind
Conservation

The understanding that quantity stays the same when appearance changes, such as water poured into a taller glass. This ability typically develops in middle childhood, not in the preschool years.

Related: Preoperational stage
Theory of mind

The growing ability to recognize that other people have their own thoughts, beliefs, and feelings that may differ from one's own. It supports empathy, pretend play, and successful peer interaction.

Related: Egocentrism, Social-emotional competence
Zone of proximal development

Vygotsky's term for the range of tasks a child can do with adult or peer help but not yet alone. Instruction is most effective when aimed at this range.

Related: Scaffolding, Social learning
Scaffolding

Temporary support an adult or capable peer gives a child to complete a task just beyond their independent ability, then gradually withdraws as competence grows. It may include hints, modeling, or breaking tasks into steps.

Related: Zone of proximal development, Differentiated instruction
Attachment

The emotional bond an infant forms with primary caregivers, shaping expectations about safety and relationships. Secure attachment supports exploration, self-regulation, and later peer relationships.

Related: Separation anxiety, Temperament
Separation anxiety

Distress a young child shows when parted from a familiar caregiver, common in toddlerhood and often resurfacing at preschool entry. Predictable routines and gradual transitions help ease it.

Related: Attachment, Transition
Temperament

A child's inborn style of reacting and self-regulating, such as activity level, mood, and adaptability. Understanding temperament helps teachers match expectations and support rather than label children.

Related: Attachment, Self-regulation
Self-regulation

The ability to manage one's emotions, attention, and behavior in order to meet a goal or follow expectations. It develops with adult co-regulation, routines, and practice rather than simple instruction.

Related: Executive function, Social-emotional competence
Executive function

The set of mental skills that support planning, holding information in mind, and inhibiting impulses. These skills grow rapidly in early childhood and are strengthened through play, songs, and turn-taking games.

Related: Self-regulation, Play-based learning
Social-emotional competence

The skills children need to understand and express feelings, form relationships, cooperate, and resolve conflicts. It is taught through modeling, coaching, and structured opportunities to practice.

Related: Theory of mind, Self-regulation
Play-based learning

An approach in which children learn through self-directed and guided play rather than only direct instruction. Play supports language, problem solving, social skills, and motivation.

Related: Executive function, Learning centers
Learning centers

Designated classroom areas, such as blocks, art, dramatic play, or books, where children choose activities that target specific skills. Centers support independence, small-group teaching, and integrated learning.

Related: Play-based learning, Differentiated instruction
Developmentally appropriate practice

Teaching that matches children's age, individual characteristics, and social or cultural context. It balances what is known about typical development with what is known about each child.

Related: Differentiated instruction, Whole child approach
Differentiated instruction

Planning lessons with varied materials, grouping, and levels of support so children with different skills can work toward the same learning goal. It responds to readiness, interests, and learning profiles.

Related: Scaffolding, Developmentally appropriate practice
Whole child approach

An approach that attends to a child's academic, physical, social, emotional, and creative growth together rather than focusing narrowly on one area. It assumes these areas influence each other.

Related: Developmental domains, Developmentally appropriate practice
Emergent literacy

The early reading and writing behaviors that develop before formal instruction, such as handling books, scribbling, and recognizing environmental print. These foundations predict later reading success.

Related: Phonological awareness, Print awareness
Phonological awareness

The ability to hear and work with the sounds of spoken language, including syllables, rhymes, and individual sounds. It is an oral skill and a strong predictor of later decoding.

Related: Phonemic awareness, Emergent literacy
Phonemic awareness

The most specific level of phonological awareness: the ability to identify and manipulate individual sounds in spoken words, such as blending or segmenting. It involves sound, not letters.

Related: Phonological awareness, Phonics
Phonics

Instruction that teaches the relationship between letters and the sounds they represent in written words. It differs from phonemic awareness, which works only with spoken sounds.

Related: Phonemic awareness, Print awareness
Print awareness

A child's understanding of how print works, including that text carries meaning, is read left to right, and consists of letters, words, and spaces. Shared reading builds this knowledge.

Related: Emergent literacy, Concepts of print
Formative assessment

Ongoing gathering of information during learning, through observation, questioning, or work samples, to adjust teaching in the moment. It is used to inform instruction rather than to assign a final grade.

Related: Summative assessment, Observation records
Summative assessment

Evaluation of learning at the end of a unit or period to determine what a child has achieved. In early childhood it is often reported through portfolios and developmental summaries.

Related: Formative assessment, Portfolio assessment
Observation records

Written notes describing what a child actually does and says, recorded objectively and without judgment. They provide evidence for planning and for communicating with families.

Related: Formative assessment, Anecdotal record
Anecdotal record

A brief, factual account of a specific incident or behavior observed at a particular time. Records are most useful when they separate description from interpretation.

Related: Observation records, Portfolio assessment
Portfolio assessment

A purposeful collection of a child's work and observations gathered over time to show growth and achievement. It supports family conferences and captures progress that tests may miss.

Related: Summative assessment, Observation records
Developmental screening

A brief, standardized check to identify children who may need further evaluation in areas such as language, motor, or social skills. It is not a diagnosis and is followed by referral when concerns appear.

Related: Atypical development, Family referral process
Authentic assessment

Assessment based on real classroom activities and everyday tasks rather than artificial testing conditions. It reflects what children can do in familiar contexts.

Related: Portfolio assessment, Formative assessment
Confidentiality

The professional obligation to protect children's and families' private information and share it only with those who have a legitimate need. It applies to records, conversations, and photographs.

Related: Family referral process, Professional ethics
Professional ethics

The standards of conduct expected of educators, including honesty, fairness, safety, and respect for families. Ethical codes guide decisions when obligations conflict.

Related: Confidentiality, Mandated reporting
Mandated reporting

The legal duty of educators to report suspected child abuse or neglect to the designated agency promptly. Teachers do not investigate; they report reasonable suspicion.

Related: Professional ethics, Confidentiality
Family referral process

The steps used to connect a family with outside services, such as developmental evaluation or community supports, after a concern is identified. It includes consent, clear communication, and follow-up.

Related: Developmental screening, Confidentiality
Family engagement

Building respectful, two-way partnerships with families so they are involved in their child's learning and feel welcome at school. It goes beyond one-way communication such as notices home.

Related: Cultural responsiveness, Transition
Cultural responsiveness

Teaching that recognizes and values children's and families' cultures, languages, and experiences, and uses them as resources for learning. It includes examining one's own assumptions.

Related: Family engagement, Developmentally appropriate practice
Transition

The process of helping children move between settings, such as home to preschool or preschool to kindergarten, with continuity and reduced stress. Advance preparation and family involvement ease adjustment.

Related: Separation anxiety, Family engagement
Individualized Education Program

A written plan developed by a team for a child who qualifies for special education services, stating goals, supports, and placement. Teachers implement it and contribute observations to team reviews.
