Which case highlighted the need for proper assessment in identifying students with intellectual disabilities?

The case that highlighted the need for proper assessment in identifying students with intellectual disabilities is Guadalupe v. Temple School District. This case is significant because it emphasized the importance of ensuring that students are assessed fairly and accurately, particularly regarding their cultural and linguistic backgrounds. The court ruled that standardized tests, which were often biased, should not be the sole basis for determining a student's eligibility for special education services. As a result, this case brought attention to the necessity of using appropriate assessment tools and methods tailored to the diverse needs of students, ultimately influencing how schools approach the identification and assessment of students with intellectual disabilities.

In contrast, while the other cases mentioned also address various aspects of educational equity and rights for students with disabilities, they do not specifically focus on the assessment processes for identifying intellectual disabilities as prominently as Guadalupe v. Temple School District does.
