What minimally should be included in any program model for English Language Learners?
Any program model for English Language Learners (ELLs) should include the following essential components:

1. Language Instruction: ELL programs should provide systematic and explicit instruction in English language skills, including speaking, listening, reading, and writing. Instruction should be tailored to the proficiency level and specific needs of the students.

2. English Language Development (ELD): ELLs require dedicated instructional time focused on developing their English language proficiency. This includes explicit instruction in vocabulary, grammar, pronunciation, and language structures.

3. Sheltered Instruction: Sheltered instruction involves adapting content instruction to make it more accessible to ELLs. Teachers use techniques such as visual aids, simplified language, and hands-on activities to support comprehension and language acquisition.

4. Differentiated Instruction: ELL programs should employ strategies that differentiate instruction based on individual student needs. Teachers should consider students' language proficiency levels, cultural backgrounds, and prior knowledge when planning and delivering lessons.

5. Culturally Responsive Teaching: Recognizing and valuing the cultural backgrounds and experiences of ELLs is crucial. Teachers should incorporate culturally relevant materials, incorporate students' native languages when appropriate, and create a supportive and inclusive learning environment.

6. Assessment and Progress Monitoring: Regular assessment of students' language proficiency and academic progress is essential. Valid and reliable assessment tools should be used to determine students' language levels, identify areas of growth, and inform instructional decisions.

7. Parent and Community Engagement: Involving parents and the wider community is critical for supporting ELLs' language development. Communication with parents should be in their preferred language whenever possible, and opportunities for parent involvement and collaboration should be provided.

8. Professional Development: Ongoing professional development for teachers working with ELLs is vital to ensure effective instruction. Teachers should receive training in strategies for language instruction, cultural responsiveness, and supporting academic content learning for ELLs.

9. Inclusive Learning Environment: ELL programs should promote an inclusive and supportive environment where students feel safe and valued. Opportunities for collaboration, peer interaction, and cross-cultural understanding should be fostered.

10. Resources and Materials: Access to appropriate instructional resources, including English language learning materials, bilingual resources, and technology tools, should be provided to support ELLs' language development and content learning.
Are these universally required in the program model everwhere? If not, where is this the minimum requirement?
While the components mentioned are essential for effective English Language Learner (ELL) programs and are recommended best practices, their implementation may vary based on factors such as local educational policies, resources, student demographics, and the specific needs of ELLs in different regions or countries.

Countries or regions with a significant population of ELLs and established language education policies are more likely to have comprehensive ELL programs that incorporate these components. For example, countries with many immigrants or refugees may have well-developed ELL programs to support the language development and academic success of newcomer students.

On the other hand, in regions with a smaller population of ELLs or limited resources, ELL programs may face challenges in providing all the components mentioned above. In such cases, schools and educators may focus on prioritizing the most critical aspects of language instruction and support, depending on their available resources.

Additionally, the terminology used to describe ELL programs may vary across countries. In some places, these programs are referred to as English as a Second Language (ESL) programs, English Language Support (ELS) programs, or bilingual education programs.
