A 21st century assessment is multiple-methods because it is an assessment continuum that includes a spectrum of strategies to different lessons. So, if I am teaching sports then I can have a lot of methods in introducing the topic that students would enjoy.
As what I have observed, 21st century assessment is systemic because it is part of a comprehensive and well-aligned assessment system that is balance and inclusive of all students, constituents and stakeholders and design to support improvement at all levels.
A 21st century assessment is technically-sound because adjustments and accommodations are made in the assessment process to meet the students needs and fairness which ar very essential and crucial for this present situation in different schools.
And the last but not theleast, a 21st century assessment is media-driven because it is filled with pro-mediaactivities, instructional/ assessment strategies are adaptive, audience isattentive, collaborative approaches is present, and is mostly effective with technology-usedtools and data sources.
