System and method for improved cumulative assessment
First Claim
1. A method for generating an ability estimate for an assessment subject comprising:
- administering to the assessment subject a first assessment at a first time T1, the first assessment including one or more items;
scoring responses by the assessment subject to the items of the first assessment;
administering to the assessment subject one or more subsequent assessments at one or more subsequent times T2- TN, each subsequent assessment including one or more items;
scoring responses by the assessment subject to the items of each of the subsequent assessments;
selecting a group of included items comprising one or more items from said first assessment and one or more items from each of at least one of said subsequent assessments, wherein the included items are related to the ability being estimated; and
computing an ability estimate for the assessment subject at any time of the administered assessments T1-TN based on scores of the group of included items.

Abstract
A system and method for improved cumulative assessment provide for automatically, e.g., programmatically, determining an evaluation of two or more assessments including two or more related items in a cumulative manner. In one embodiment, an initial assessment including initial assessment items is administered at time T1 and scored to produce an ability estimate. At least one successive assessment is also administered and scored to produce an ability estimate. Selected ones of the administered assessments or included items are determined (“included assessments”), and the included assessments are scored to produce a simultaneous maximum likelihood ability estimate for the included assessments, for example, in view of all of the included assessments.

13. A system for generating an ability estimate for an assessment subject comprising:
-
a test administration module adapted to administer to the assessment subject a first assessment at a first time T1, the first assessment including one or more items, and to administer to the assessment subject one or more subsequent assessments at one or more subsequent times T2-TN, each additional assessment including one or more items;
a scoring module adapted to score responses by the assessment subject to the items of the first and subsequent assessments;
an item selection module adapted to select a group of included items comprising one or more items from said first assessment and one or more items from each of at least one of said additional assessments, wherein the included items are related to the ability being estimated; and
an ability estimate engine adapted to compute an ability estimate for the assessment subject at any time of the administered assessments T1-TN based on scores of the group of included items. - View Dependent Claims (14, 15)

16. A method for generating a cumulative ability estimate for an assessment subject comprising:
-
administering to the assessment subject an initial assessment at an initial time, the initial assessment including initial assessment items;
generating an initial ability estimate for the assessment subject for the initial time based on responses to the initial assessment items related to the ability being estimated;
administering to the assessment subject at least one successive assessment at a time different from the initial time, the successive assessment including successive assessment items including items having measurement goals that are related to measurement goals of the initial assessment items;
generating a successive ability estimate for the assessment subject for the different time based on responses to the successive assessment items related to the ability being estimated;
selecting two or more assessments of the initial and at least one successive assessment to be included in an improved likelihood ability estimate;
selecting assessment items from the two or more selected assessments to be included in the improved likelihood ability estimate and excluding non-selected items from the improved likelihood ability estimate; and
generating improved likelihood ability estimates for the assessment subject for the initial time and for the different time based on the responses to the selected assessment items. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
