## Background
BACKGROUND
1. Field of the Invention
The disclosure generally relates a method and apparatus for an automated competency assessment system and a method thereof. More particularly the present invention relates to an automated system for talent acquisition in an enterprise to identify talented candidates who meet the qualification standards specified by enterprise using a secured and light weight method of providing content including questions and responses in a distributed architecture.
2. Description of Related Art
For many years standardized testing has been common method of assessing examinees for the purpose of education, job placements, skill evaluation etc. Due to cost and complexity of tests, computer based testing emerged as a superior method for providing standardized tests but administration of test and evaluation of test results dynamically at a large scale still pose variety of problems like redundancy of questions and lack of harmonization, analytics and scale up.
The need to effectively test and analyze the large pools of candidates for the purpose of talent acquisition or educational assessment has also been long recognized. With increasingly sophisticated workforces of correspondingly increasing accumulated value, the process of testing, analyzing and recruiting a workforce, with effective real-time analytics, can preserve and deliver substantial value to organizations, including employer enterprises and placement agencies.
Several inventions have been made in this domain some of them known to us are described below:
U.S. Pat. No. 7,437,309 describes a computer based human capital management system that collects information from any combination of position applicants, employees, and reserve pool talent reflective of the position skills, performance, and requirements thereof. In particular, the invention discloses a method for implementing a talent management system, executed on a computer system, providing for the collection and qualification of performance capability information of workforce candidates. The invention however relies on the information collected from the candidates and fails to present a system for secure administration of real-time assessment of candidates in a scalable way.
US Patent Application 20070185757 describe a method for performing Talent Relationship Management (TRM) of candidates. It uses target groups formed for specified purposes from candidates constituting a talent pool. In particular the invention discloses a method of identifying potentially suitable candidates based on stored and organized information sources for filling a vacancy in an organization. In one embodiment, this patent application proposes TRM in distributed computing environments. In another embodiment, it discloses a method that checks skill level and specialty, experience, geographical location of candidate, candidate's aptitude and interests. However, the invention fails to present a system for secure administration of real-time assessment of candidates at several locations in a scalable way.
An automated process for recruiting technicians and pre-certifying them for a job position in distributed over a number of different geographical locations e.g., franchises is disclosed in US Patent Application 20070192172. The process as described in the patent application is controlled from a main office or central station, at a computer or computer server that is connected with a global computer network such as the Internet. However, the invention fails to disclose a system that maintains security of process and transfer of data. The invention also fails to propose a method of assessment where no two candidates are given tests with same questions and yet the questions are of standardized difficulty level and also does not disclose a real-time analytics of the performance of the candidates.
US Patent Application 20020156674 describes a recruiting system and method for providing job offer information via a server connected to a network. is the invention proposes a skill information database for storing skill information concerning skilled people requiring jobs; and an aptitude level determiner for determining an aptitude level for a skill required for each job. The invention fails to disclose a method of secure and scalable test administration.
All the above-mentioned prior-arts fail to disclose a secure and scalable solution to automate the application of competency assessment by providing appropriate level of security to the process and data transfer. The prior art discussed above also fails to attempt the requirements of exclusivity and standardization of the assessment, wherein no two candidates are given tests with same questions and yet the question are of standardized difficulty level. There is also a “long felt need” to solve the vacuum of powerful and real-time analytics in this domain of knowledge assessment systems.
In order to solve the above problems this invention proposes an automated system for competency assessment to identify talented candidates, wherein the system is architected as a scalable, secure and light weight system, designed to operate over a distributed architecture, and provides secure content, including questions and responses, wherein the distinctiveness of the test is maintained and the analysis of the test results is supported at a near real time by powerful analytics engine.
Therefore, there is a need for a method and apparatus for an automated competency assessment tool.

        h. Central data centre server improves the quality of the content from the analysis of the response data.
    
    


The invention thus enables:

    
    
        a. One or more exam centre servers to connect to the central data centre server to receive the online test software bundle for automatic installation over the communication network on successful authentication by the data centre server.
        b. One or more exam centre server to connect to the central data centre server to receive the encrypted and secure online test content over the communication network based on successful authentication by the data centre server
        c One or more candidates to take the exam from exam centers by connecting to the exam centre server simultaneously over the communication network.
    
    


The scalability and load management at the exam centre server is achieved through an innovative batching mechanism that groups candidates automatically into small batches called slots. Batching also aids in making the testing process and the results generation process a continuous and efficient assembly line activity, facilitating the option of sharing test information with the central data centre server as small packets of encrypted information, and generating results from the central data centre server instantaneously.
The invention enables the method of:

    
    
        a. Obtaining assessor input defining the required knowledge level to be tested
        b. Definition of smart test questions to assess definition set of skills
        c. categorization of questions at multiple levels of abstraction
        d. assembling and representation of questions to form online test content based on the assessor input
    
    


Online test content received from the central data centre is decrypted at the exam centre to generate a standardized question paper for each candidate. The tests at each candidate system are synchronized with the exam centre server.
In particular, the system provides a secure setup and a method of transfer of test information, such as the content for the test (question paper content) and the test result information, using AES encryption, RSA encryption and advanced compression techniques from the centralized locations to the distributed test centers and vice versa over the communication network.
The test and feedback information is consolidated for each candidate at the exam centre server and securely transferred to the central data centre server for result generation.
In one embodiment of the invention the online test content is stored in ‘RAM’ in the form of objects and not persisted in a database and is not physically retrievable from any storage device such as the hard disk at the exam centre.
The invention enables the prevention of the loss of test content through a backup and restore mechanism that consolidates and backs up data stored in the ‘RAM’ in situations of network or power failures and restores the data back on restoration of network/power and aids in resuming the test without any errors.
The Invention further enables the consolidation of test results for each completed exam slot and generates the results of the test conducted with help of the system as described which is instantaneous and secure.

Another aspect of the invention provides a bundle of assessment services accessible over the communication network to provide secure, digitized testing and hiring solutions. Customers may use either the complete system or modules, through the data centre. The knowledge Centre is a secure and intelligent source of questions, wherein questions are categorized and organized by concepts, skills and domains. Questions generated by the Knowledge centre are packaged into a question paper that enables selection of candidates with a certain desired skills or set of skills.
FIG. 1 is a block diagram of the system comprising of different components to automate the assessment or recruitment process in an enterprise according to one embodiment of the invention wherein the system (105) provides scalable, secure assessment of knowledge to one or computer candidates (130) comprising a data centre (115), a knowledge centre server (110), an exemplary exam centre server (120) and an analytics engine (125) wherein:
the data centre server (115) is a centralized control to remotely manage and moderate the assessment or recruitment process in an enterprise.
the knowledge centre server (110) component consists of a secure interface to assemble and represent standardized questions
the exam centre server (120) consists of a decentralized system for conducting tests at multiple locations in a secure manner and sending the encrypted test information to the data centre server.
the analytics engine (125) provides analytics on the data, performance of candidates
FIG. 2 is a flow chart illustrating how the encryption and decryption of the test paper and results can be done.
In an embodiment of the Invention the present Invention is a secured method of providing content including questions and responses in a distributed architecture. In the step (305), an advanced encryption standard (AES)(www.aes.com) symmetric key algorithm encrypts the test information to provide a security to test contents. In the step (315), advanced encryption standard (AES) symmetric key algorithm requires a key that can be used for both encryption and decryption of the information. In the step (325), the key which is used to encrypt the question paper using the AES algorithm at the data centre is generated dynamically at the data centre. In the step (335), for giving one more level of security, RSA (Rivest, Shamir and Adleman)(www.rsa.com) algorithm applies to encrypt the key that is used to encrypt the question paper. Then, in next step (345), the test location generates both public and private key at the time of test configuration. The public key alone is shared with the data centre, which uses this public key to encrypt the AES key used in encryption of the question paper is shown in (355), whereas the private key is retained at the test location to decrypt the encrypted AES key which is securely transmitted over the network along with the question paper after compression. In next step (375), after getting the AES key by decryption at the test centre, it can be used to decrypt the question paper that has been encrypted with the AES key.
FIG. 3 is an illustration of workflow of an exemplary application of the invention.
The Human Resource manager requests for testing services to conduct competency assessment (1). The request is approved by the service manager installation (2). The software is dispatched to the Human Resource manager (3). The software is installed upon successful (4) The Human Resource manager can request for the contents from the data centre (5). On approval, questions are packaged into an encrypted question paper through Advanced Encryption Standard (AES) algorithm (6). The computational devices can then be taken to the site of the test where automatic infrastructure and software compliance is undertaken (8). On the day of the exam, the test is configured by connecting to the Data Centre, from where the encrypted question paper is received upon authentication (9). The test is then taken one or more candidates (10). On completion of the test, the encrypted results are uploaded to the data centre where they are stored and published (11). Analytics of the test results are available real time (12).
FIG. 4 is an illustration of the system architecture as per the present invention.
The component (100) represents the data centre server which is connected over the network with the knowledge centre and various exam centre servers. The data centre provides the technology services including secure encrypted question paper to the Exam centre upon authentication. The component (200) refers to the Knowledge centre server managed by one or more content services expert, the knowledge centre server is configured to communicate to the data centre server over the communication network. The component (300) of the illustration refers to the Exam centre component connected to candidate computers and configured to share content, including authentication data, question paper data, online test data and result data with data centre server. Exam centre server(s) also communicate the question papers to various candidate computing devices. The component (400) and (500) refer to client systems and candidates respectively that take the test over the communication network.
FIG. 5 is a flowchart of the workflow of amongst Data Centre, Knowledge Centre and Exam Centre based on the system architecture of the present invention.
According to one embodiment of the invention, provides a bundle of assessment services accessible over the communication network to provide secure, digitized testing and hiring solutions. Customers may use either the complete system or modules, through the data centre. According to one embodiment of the invention, the knowledge Centre server is a secure and intelligent source of questions, wherein questions are categorized and organized by concepts, skills and domains. Questions generated by the Knowledge centre are packaged into a question paper that enables selection of candidates with a certain desired skills or set of skills.
According to one embodiment of the invention to conduct a test in a scalable way where many users can take the exams at any given time such that no two users are given tests with the same questions and yet the tests are of standardized difficulty level. This is because the architecture is such that the load of the candidates taking tests is distributed across local servers called the Exam Centers. Also, there is no database residing on the Exam Centre. The Exam Centre interacts directly with the data centre to receive an encrypted, abstract question paper which it later renders into multiple candidate consoles taking the exam.
Also, the test is in abstract form, therefore the question paper presented to the candidate is unknown until the exam results the time of the test. This ensures security against question leaks. Similarly results are also securely compressed, encrypted and then transmitted. Hence, tampering of the results is impossible.
It is required by large organizations and educational institutes to have common entrance tests for a large number of candidates across multiple locations. It is hence required that the tests presented to the candidates be standardized and of uniform or identical difficulty levels. However, the system is also required to discourage candidates from copying solutions to test problems from a neighboring test taker. Hence the mechanism of problem formulation and test creation is such that it discourages candidates from even attempting to copy or share solutions to problems either during the test or after it and also ensures that the test is standardized.
According to one embodiment of the invention, an online test data is stored in the form of java objects in the memory. These objects can be serialized and stored as flat files during the back-up process. The idea of storing the data in the form of an object and not database is because the database requires space and maintenance. On the other hand, use of a persistent database would cause the application to be heavy, and would require trained personnel to setup and administer the database. To create a fair testing process where tests can be backed up in case of failures such as network interruption or power failure and these tests can be resumed without loss of data. In many cities across India, power failure is a natural and frequently occurring phenomenon. Hence the test requires mechanisms to ensure that a candidate's test state is saved and can be restored in the event of such a failure.
According to one embodiment of the invention, the system uses compression methods provided by Java. These compression techniques work by scanning text, replacing and indexing repeating strings, thereby reducing file size. In our present invention, the document is in XML format. XML documents contain noise, which are repeating and long tags, that provide syntax and semantic structure to the data. This compression noise can further be reduced by reducing the size of the tags and indexing them. This, along with a standard compression technique works effectively, particularly in situations where file upload and download have to take place within a relatively short period of time.
According to another embodiment of the invention, the analytics engine performs various functions by gathering information from calibration and live tests. It performs predictive hiring, provides valuable feedback to the question bank and properties and also provides us with meta-cognitive indicators of the crowd. It helps perform social, demographic, location-based and temporal analysis on the population. Also, the system provides powerful analytics at multiple levels to the various stakeholders of the system.
According to one embodiment of the invention, the system's services can be provided on net books, mobile phones, digital paper and other computational devices. Since organizations need to spot and nurture talent from hitherto unfamiliar talent pools, they require administrators to travel to remote locations and administer tests under strange and unfamiliar conditions. Various forms of test administering methods are hence required, that are mobile, low-cost, easy-to-use and failure-proof. Hence different forms of test taking solutions are provided. For example, if the location does not have a network and computer infrastructure, the test administrator can conduct the exam on a digital pen and paper or even a mobile handheld.
According to one embodiment of the invention, the system provides services that consist of multiple offerings like the question bank content, online testing service, analytics and feedback of results which can independently offered as a solution or can be packaged in various combinations as a solution. Each of these offerings will independently evolve into other business offerings. For example the question bank content offering can evolve into a web-based education offering that will be used as a self-learning tutorial to learn, test knowledge and obtain real-time feedback on different functional domains of interest.
The system is self-learning in the manner that it learns and reacts by analyzing the test content data and results. It provides periodic identification of the questions which need to be eliminated from the knowledge centre upon receiving the number of correct responses to the question has sharply increased on the feedback data.
According to one embodiment of the invention, the system inherently ensures process compliance with complete audit and traceability of processed to responses in every single question. There are checks at every point in the process. Therefore, it ensures a fair, auditable and traceable test process.
It is yet another objective of the present invention to provide multiple offerings like the question bank content, online testing service, analytics and feedback of results which can independently offered as a solution or can be packaged in various combinations as a solution. Further, each of these offerings will independently evolve into other business offerings. For example the question bank content offering can evolve into a web-based education offering that will be used as a self-learning tutorial to learn, test knowledge and obtain real-time feedback on different functional domains of interest.
The invention is described in the example given below which is provided only to illustrate the invention and therefore should not be construed to limit the scope of the invention.
An organization XYZ wants to hire 20,000 candidates in a recruitment drive that has to be carried out in 400 locations on a single day wherein more than half a million candidates have to appear. The organization wants to conduct a harmonized aptitude test for making hiring decisions.
In normal circumstances the organization will have to mobilize huge human resources to compile, supervise, undertake and analyze such an operation. Where as according to the present invention, the data centre server will first obtain a user input defining the required knowledge level to be tested and domain of the test from the recruiter. In the next step the system at each distributed exam centre will request software and data for conducting competency assessment from the data centre. Upon successful authentication, the software is installed in the distributed exam centers. In the following step, the LanScape component of the system will confirm the infrastructure, network and software availability at each test location required for conducting test securely with the help of computer program. In the next step, the test is configured at the Exam centre server by connecting to the Data Centre server, from where the encrypted online test content is received on successful authentication. Exam centre server decrypts the online test content and sends unique and standardized question paper to each candidate computational device.
